Answer:
x = 4
9(4) + 3 = 39
8(4) + 1 = 33
Step-by-step explanation:
Simplify
9x + -3 = 8x + 1
Reorder the terms:
-3 + 9x = 8x + 1
Reorder the terms:
-3 + 9x = 1 + 8x
Solving
-3 + 9x = 1 + 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.
-3 + 9x + -8x = 1 + 8x + -8x
Combine like terms: 9x + -8x = 1x
-3 + 1x = 1 + 8x + -8x
Combine like terms: 8x + -8x = 0
-3 + 1x = 1 + 0
-3 + 1x = 1
Add '3' to each side of the equation.
-3 + 3 + 1x = 1 + 3
Combine like terms: -3 + 3 = 0
0 + 1x = 1 + 3
1x = 1 + 3
Combine like terms: 1 + 3 = 4
1x = 4
Divide each side by '1'.
x = 4
Simplify
x = 4
