Simplifying 7(x + -3) = (x + 2) Reorder the terms: 7(-3 + x) = (x + 2) (-3 * 7 + x * 7) = (x + 2) (-21 + 7x) = (x + 2) Reorder the terms: -21 + 7x = (2 + x) Remove parenthesis around (2 + x) -21 + 7x = 2 + x Solving -21 + 7x = 2 + x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1x' to each side of the equation. -21 + 7x + -1x = 2 + x + -1x Combine like terms: 7x + -1x = 6x -21 + 6x = 2 + x + -1x Combine like terms: x + -1x = 0 -21 + 6x = 2 + 0 -21 + 6x = 2 Add '21' to each side of the equation. -21 + 21 + 6x = 2 + 21 Combine like terms: -21 + 21 = 0 0 + 6x = 2 + 21 6x = 2 + 21 Combine like terms: 2 + 21 = 23 6x = 23 Divide each side by '6'. x = 3.833333333 Simplifying x = 3.833333333
