4x + 3x -7= 60 - 2x - 13

x = 6

Step-by-step explanation: Simplifying

4x + 3x + -7 = 60 + -2x + -13

Reorder the terms:

-7 + 4x + 3x = 60 + -2x + -13

Combine like terms: 4x + 3x = 7x

-7 + 7x = 60 + -2x + -13

Reorder the terms:

-7 + 7x = 60 + -13 + -2x

Combine like terms: 60 + -13 = 47

-7 + 7x = 47 + -2x

Solving

-7 + 7x = 47 + -2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2x' to each side of the equation.

-7 + 7x + 2x = 47 + -2x + 2x

Combine like terms: 7x + 2x = 9x

-7 + 9x = 47 + -2x + 2x

Combine like terms: -2x + 2x = 0

-7 + 9x = 47 + 0

-7 + 9x = 47

Add '7' to each side of the equation.

-7 + 7 + 9x = 47 + 7

Combine like terms: -7 + 7 = 0

0 + 9x = 47 + 7

9x = 47 + 7

Combine like terms: 47 + 7 = 54

9x = 54

Divide each side by '9'.

x = 6

Simplifying

x = 6

6

Step-by-step explanation:

combine the 2 X's on the left side of the equation which is 4x+3x=7x. now your equation is 7x-7=60-2x-13. now you gotta combine the 60 and -13, s0 60-13=47. now your equation is 7x-7=47-2x now you move -2x to the left side of the equation you have to change the sign so now its 2x+7x-7=47 and you gotta combine the two x's on the left so its gonna be 9x-7=47. next you have to move the -7 to the right and change the sign. now your equation is 9x=47+7 which is 54 and now your equation is 9x=54 then you have to move the 9 to the right but you have to change is to division so now its x=54/9 which is 6 so now your answer is x=6
