Simplifying
6(3x + -5) + -7x = 25
Reorder the terms:
6(-5 + 3x) + -7x = 25
(-5 * 6 + 3x * 6) + -7x = 25
(-30 + 18x) + -7x = 25
Combine like terms: 18x + -7x = 11x
-30 + 11x = 25
Solving
-30 + 11x = 25
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '30' to each side of the equation.
-30 + 30 + 11x = 25 + 30
Combine like terms: -30 + 30 = 0
0 + 11x = 25 + 30
11x = 25 + 30
Combine like terms: 25 + 30 = 55
11x = 55
Divide each side by '11'.
x = 5
Simplifying
x = 5
