Answer:
Step-by-step explanation:
Simplifying
(9x + -6) + (-5x + 7) = 0
Reorder the terms:
(-6 + 9x) + (-5x + 7) = 0
Remove parenthesis around (-6 + 9x)
-6 + 9x + (-5x + 7) = 0
Reorder the terms:
-6 + 9x + (7 + -5x) = 0
Remove parenthesis around (7 + -5x)
-6 + 9x + 7 + -5x = 0
Reorder the terms:
-6 + 7 + 9x + -5x = 0
Combine like terms: -6 + 7 = 1
1 + 9x + -5x = 0
Combine like terms: 9x + -5x = 4x
1 + 4x = 0
Solving
1 + 4x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + 4x = 0 + -1
Combine like terms: 1 + -1 = 0
0 + 4x = 0 + -1
4x = 0 + -1
Combine like terms: 0 + -1 = -1
4x = -1
Divide each side by '4'.
x = -0.25
Simplifying
x = -0.25
