You're trying to figure out the value of "x."

How is that even hard
I can literally do this in my-No.

Look, if you need help, I'll explain it to you, since you're probably new to it.

Your goal is to isolate the variable, x.

Since you are going in reverse order of operations, you first subtract 1 from 7, as you are reversing the addition. So, you get 3x=6
Second, you divide 6 by 3, getting x=2.

No. X is only seven when we multiply it by three and then add one, as states the problem.

3x2+1

because through having the answer you determine the value of the variable because you can substitute x for a 2 and it would make sense as other numbers would not


so x = 2



i dont know why i spent time explaining this

You want to isolate the variable "x."

"x" is not equal to 7, as you have claimed it to be. "3x + 1" is equal to 7.

You want to find out what "x" is by using something called "inverse operations" to isolate the variable, or to move all of the stuff except for "x" to the other side.

3x + 1 = 7

First, we want to move the 1 to the right side. Because 1 is being added, we can use the inverse operation of adding, which is subtracting, and subtract 1 from both sides of the equation.

3x + 1 - 1 = 7 - 1

3x = 6

Now, since x is being multiplied by 3, we want to use the inverse operation of multiplying, which is dividing, to get the 3 over to the other side.

3x / 3 = 6 / 3

x = 2.

Hopefully my explaination will be beneficial to you.

Here are some things to take note on:

1. Inverse Operations:

Adding is the inverse operation of Subtracting, and vice-versa.

Multiplying is the inverse operation of Dividing, and vice-versa.

Raising to the nth power is the inverse operation of finding the nth root, and vice-versa.

2. Properties of Equality:

Addition Property of Equality - If you add something to one side of an equation, you must add the same thing to the other side of the equation for the equation to remain equal.

Subtraction Property of Equality - If you subtract something from one side of an equation, you must subtract the same thing from the other side of the equation for the equation to remain equal.

Multiplication Property of Equality - If you multiply one side of the equation by something, you must multiply the other side of the equation by the same thing for the equation to remain equal.

Division Property of Equality - If you divide one side of the equation by something, you must divide the other side of the equation by the same thing for the equation to remain equal.
