User: Solve for x. 3(x + 5) - 2(x + 2) = 20 1 9 13

Weegy: Simplifying -6x + -2 = 40 Reorder the terms: -2 + -6x = 40 Solving -2 + -6x = 40 Solving for variable 'x'. Move all terms containing x to the left, [ all other terms to the right. Add '2' to each side of the equation. -2 + 2 + -6x = 40 + 2 Combine like terms: -2 + 2 = 0 0 + -6x = 40 + 2 -6x = 40 + 2 Combine like terms: 40 + 2 = 42 -6x = 42 Divide each side by '-6'. x = -7 Simplifying x = -7 ]

3(x + 5) - 2(x + 2) = 20
3x + 15 - 2x - 4 = 20
3x - 2x = 20 -15 + 4
x = 9

The equation 3x + 1 = 3x + 2 has no solution.
3x + 1 = 3x + 2;
3x - 3x = 2 - 1;
0 = 1
