- 7x + (9x - 3) = - 7x + 9x - 3 = 2x - 3
9x-8=7x-3 9x-7x=-3+8 2x=5 x=5/2 x=2.5
Simplifying 2x + 3 = 9x Reorder the terms: 3 + 2x = 9x Solving 3 + 2x = 9x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9x' to each side of the equation. 3 + 2x + -9x = 9x + -9x Combine like terms: 2x + -9x = -7x 3 + -7x = 9x + -9x Combine like terms: 9x + -9x = 0 3 + -7x = 0 Add '-3' to each side of the equation. 3 + -3 + -7x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -7x = 0 + -3 -7x = 0 + -3 Combine like terms: 0 + -3 = -3 -7x = -3 Divide each side by '-7'. x = 0.4285714286 or x = 3/7 Simplifying x = 0.4285714286 or x = 3/7
7x = 4x - 93x = -9x = -3
