Step-by-step explanation:
Simplifying
3(5x + -7) + -2(9x + -11) = 4(8x + -13) + -17
Reorder the terms:
3(-7 + 5x) + -2(9x + -11) = 4(8x + -13) + -17
(-7 * 3 + 5x * 3) + -2(9x + -11) = 4(8x + -13) + -17
(-21 + 15x) + -2(9x + -11) = 4(8x + -13) + -17
Reorder the terms:
-21 + 15x + -2(-11 + 9x) = 4(8x + -13) + -17
-21 + 15x + (-11 * -2 + 9x * -2) = 4(8x + -13) + -17
-21 + 15x + (22 + -18x) = 4(8x + -13) + -17
Reorder the terms:
-21 + 22 + 15x + -18x = 4(8x + -13) + -17
Combine like terms: -21 + 22 = 1
1 + 15x + -18x = 4(8x + -13) + -17
Combine like terms: 15x + -18x = -3x
1 + -3x = 4(8x + -13) + -17
Reorder the terms:
1 + -3x = 4(-13 + 8x) + -17
1 + -3x = (-13 * 4 + 8x * 4) + -17
1 + -3x = (-52 + 32x) + -17
Reorder the terms:
1 + -3x = -52 + -17 + 32x
Combine like terms: -52 + -17 = -69
1 + -3x = -69 + 32x
Solving
1 + -3x = -69 + 32x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-32x' to each side of the equation.
1 + -3x + -32x = -69 + 32x + -32x
Combine like terms: -3x + -32x = -35x
1 + -35x = -69 + 32x + -32x
Combine like terms: 32x + -32x = 0
1 + -35x = -69 + 0
1 + -35x = -69
Add '-1' to each side of the equation.
1 + -1 + -35x = -69 + -1
Combine like terms: 1 + -1 = 0
0 + -35x = -69 + -1
-35x = -69 + -1
Combine like terms: -69 + -1 = -70
-35x = -70
Divide each side by '-35'.
x = 2
Simplifying
x = 2
