Answer 2

Simplifying
x15 + -64 = 0

Reorder the terms:
-64 + x15 = 0

Solving
-64 + x15 = 0

Solving for variable 'x'.

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

Add '64' to each side of the equation.
-64 + 64 + x15 = 0 + 64

Combine like terms: -64 + 64 = 0
0 + x15 = 0 + 64
x15 = 0 + 64

Combine like terms: 0 + 64 = 64
x15 = 64

Simplifying
x15 = 64

Reorder the terms:
-64 + x15 = 64 + -64

Combine like terms: 64 + -64 = 0
-64 + x15 = 0
