Solve 2x plus 3 equals 9x equals?
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
What expresssion represents the sum of (7x-3y) and (2x plus 5y)?
(7x-3y) + (2x+5y) = 9x+2y
