Answer:
Step-by-step explanation:
Simplifying
2x + -5 = 8x + 7
Reorder the terms:
-5 + 2x = 8x + 7
Reorder the terms:
-5 + 2x = 7 + 8x
Solving
-5 + 2x = 7 + 8x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8x' to each side of the equation.
-5 + 2x + -8x = 7 + 8x + -8x
Combine like terms: 2x + -8x = -6x
-5 + -6x = 7 + 8x + -8x
Combine like terms: 8x + -8x = 0
-5 + -6x = 7 + 0
-5 + -6x = 7
Add '5' to each side of the equation.
-5 + 5 + -6x = 7 + 5
Combine like terms: -5 + 5 = 0
0 + -6x = 7 + 5
-6x = 7 + 5
Combine like terms: 7 + 5 = 12
-6x = 12
Divide each side by '-6'.
x = -2
Simplifying
x = -2
