tomorrow if i don't bring it in or get it finished, i'm going to be beaten up at lunch time because everyone has to get their homework done for their reward (chinese food or kfc, whatever the class chooses)
she taught us a method today on how to do it and i copied it down in my notes but im using it now and getting all the wrong answers, and the right way to do it is online, completely different from what she taught and takes about 20 lines to write :(
all im doing is getting wrong answers and writing didnt work next to it :( |

"46+1+8x = 18x+5" i can help, thats very simple algebra first, you'll want to take 8x and add it to 18x to make it: 46+1 = 26x+5 now you'll want to combine like terms: 47 = 26x+5 now, subtract the 5 and add it onto the 47 to make 52 = 26x 52/26 = 2 x = 2
can i have some hweat thins |

46+1+8x = 18x+5
47+8x=18x+5 8x-18x
47+-10x=5 5-47=-42 10x=-42 -42/-10x=4.2x
x=4.2x

there's many errors in this i'm short on time so i cant prove them just go to mathpapa.com for help or something. first error is you subtract 18 from 8 since when you move to other side you do opposite action. dont feel like finding rest as I have to go |

Let's solve your equation step-by-step. 46+1+8x=18x+5 Step 1: Simplify both sides of the equation. 46+1+8x=18x+5 Simplify: (Hide steps) Let's simplify step-by-step. 46+1+8x=18x+5 (8x)+(46+1)=18x+5(Combine Like Terms) 8x+47=18x+5 8x+47=18x+5 Step 2: Subtract 18x from both sides. 8x+47−18x=18x+5−18x −10x+47=5 Step 3: Subtract 47 from both sides. −10x+47−47=5−47 −10x=−42 Step 4: Divide both sides by -10. −10x −10 = −42 −10 x= 21 5 Answer: x= 21/5 (4.2)

@core 63 doesn't equal 41
46+1+16(which is 8*2) doesn't equal 36(which is 18*2)+5
that sounds like a personal problem |
