Answer:
Step-by-step explanation:
Simplifying
9x + -5 = 10x + -9
Reorder the terms:
-5 + 9x = 10x + -9
Reorder the terms:
-5 + 9x = -9 + 10x
Solving
-5 + 9x = -9 + 10x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10x' to each side of the equation.
-5 + 9x + -10x = -9 + 10x + -10x
Combine like terms: 9x + -10x = -1x
-5 + -1x = -9 + 10x + -10x
Combine like terms: 10x + -10x = 0
-5 + -1x = -9 + 0
-5 + -1x = -9
Add '5' to each side of the equation.
-5 + 5 + -1x = -9 + 5
Combine like terms: -5 + 5 = 0
0 + -1x = -9 + 5
-1x = -9 + 5
Combine like terms: -9 + 5 = -4
-1x = -4
Divide each side by '-1'.
x = 4
Simplifying
x = 4
