Answer

x = -4

Work Step by Step

Simplifying 11 + -3x = 23 Solving 11 + -3x = 23 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-11' to each side of the equation. 11 + -11 + -3x = 23 + -11 Combine like terms: 11 + -11 = 0 0 + -3x = 23 + -11 -3x = 23 + -11 Combine like terms: 23 + -11 = 12 -3x = 12 Divide each side by '-3'. x = -4 Simplifying x = -4
