Simplifying

15 + 8x = 7x + -8


Reorder the terms:

15 + 8x = -8 + 7x


Solving

15 + 8x = -8 + 7x


Solving for variable 'x'.


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


Add '-7x' to each side of the equation.

15 + 8x + -7x = -8 + 7x + -7x


Combine like terms: 8x + -7x = 1x

15 + 1x = -8 + 7x + -7x


Combine like terms: 7x + -7x = 0

15 + 1x = -8 + 0

15 + 1x = -8


Add '-15' to each side of the equation.

15 + -15 + 1x = -8 + -15


Combine like terms: 15 + -15 = 0

0 + 1x = -8 + -15

1x = -8 + -15


Combine like terms: -8 + -15 = -23

1x = -23


Divide each side by '1'.

x = -23


Simplifying

x = -23

Solve:

15  +    8x    =     7x     -      8

Simplify Both sides of the equation:

15   +   8x  =    7x    -   8

15     +    8x    =      7x       +         -8

8x     +    15     =    7x      -     8

Subtract  7x  from both sides:

8x    +   15    -    7x        =      7x     -     8    -     7x

x       +      15        =       -8

Subtract   15     from both sides:

x       +     15     -      15       =          -8     -    15

x           =           -23

Answer   ==========>      x          =             -23




Hope that helps!!!!                                              : )
