My answer-
Simplifying 5x + -14 = 8x + 4
Reorder the terms: -14 + 5x = 8x + 4 Reorder the terms: -14 + 5x = 4 + 8x
Solving -14 + 5x = 4 + 8x Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right. Add '-8x' to each side of the equation. -14 + 5x + -8x = 4 + 8x + -8x
Combine like terms: 5x + -8x = -3x -14 + -3x = 4 + 8x + -8x
Combine like terms: 8x + -8x = 0 -14 + -3x = 4 + 0 -14 + -3x = 4 Add '14' to
each side of the equation. -14 + 14 + -3x = 4 + 14
Combine like terms: -14 + 14 = 0 0 + -3x = 4 + 14 -3x = 4 + 14
Combine like terms: 4 + 14 = 18 -3x = 18 <span>
Divide each side by '-3'. x = -6
Simplifying x = -6
