I need help with the following:
5n - 16 - 8n = -10 n=?
x - 1 + 5x = 23 x=?
-49 + 18 - 19j = -28 j=?
-5(x - 3) = -25 x=?
-10 = 5(2w - 4) w=?
-3 = -3(2t - 1) t=?
-15 = 5(3q - 10) - 5q q=?
Please give only answers :D

"5n - 16 - 8n = -10 n=?"

1. Combine like terms

5n - 8n = -3n


2. Move the -16 to the other side of the equal sign

-3n = -10 + 16        (When you move a number from one side of the equal side to the other, it changes signs. Since the number was -16 originally, it become 16 when you switch sides)


3. Add -10 + 16

-10 + 16 = 6
-3n = 6

4. To get n all by itself you have to divide it by -3 (because you have to do the opposite operation. It was originally being multiplied, so you have to divide). Since you are dividing -3 on one side, you have to do the same thing on the other side. Divide 6 by -3.

-3n / -3 = 6 / -3

n = -2


Now try the rest on your own.

Naw, I'm giving all the work so you can see how it's done:

1) 5n - 16 - 8n = -10
Add like terms. 5n+-8n= -3n
-3n-16=-10
Add 16. 16+-10=6
-3n=6
Divide -3. 6/-3= -2
n= -2
CHECK ANSWER! Plug it in: 5(-2)-16-8(-2)= -10?
PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
5(-2)= -10 -8(-2)= 16
-10-16+16
-16+16=0
-10 left over. Equation is correct so -2 is your answer.

2) x - 1 + 5x = 23
Add like terms. x+5x=6x
6x-1=23
Add 1. 23+1=24
6x=24
Divide by 6. 24/6=4
x=4
CHECK ANSWER! Plug it in: (4)-1+5(4)=23?
PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
5(4)=20
4-1+20
4-1=3
3+20=23. Equation is correct so 4 is your answer.

3) -49 + 18 - 19j = -28
Add like terms. -49+18= -31
-31-19j= -28
Add 31. -28+31= 3
-19J= 3
Divide by -19. 3/-19= -0.15
J= -0.15
(Answer didn't add up but I can't find my mistake. If anyone can find it and fix it please do so.)

4) -5(x - 3) = -25
Divide by -5. -25/-5=5
x-3=5
Add 3. 5+3=8
x+8
CHECK ANSWER! Plug it in: -5(8-3)= -25?
PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
8-3=5
-5(5)= -25. Equation is correct so 8 is your answer.

5) -10 = 5(2w - 4)
Divide by 5. -10/5= -2
-2=2w-4
Add four. -2+4=2
2=2w
Divide by 2. 2/2=1
w=1
CHECK ANSWER! Plug it in: 5(2(1)-4)= -10?
PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
2(1)= 2-4= -2
5(-2)= -10. Equation is correct so 1 is your answer.

6) -3 = -3(2t - 1)
Divide by -3. -3/-3= 1
1=2t-1
Add 1. 1+1=2
2=2t
Divide by 2. 2/2=1
t=1
CHECK ANSWER! Plug it in: -3(2(1)-1)= -3?
PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
2(1)= 2-1= 1
-3(1)= -3. Equation is correct so 1 is your answer.

7) -15 = 5(3q - 10) - 5q
Divide by 5. -15/5= -3
-3=3q-10-5q
Add like terms. -5q+3q=-2q
-3=-2q-10
Add 10. -3+10=7
7=-2q
Divide by 2. 7/-2= -3.5
(Answer didn't add up but I can't find my mistake. If anyone can find it and fix it please do so.)

3 and 7 are the only ones that I'm concerned about but the others are perfect.
