Simplifying 2x + 2x + -15 = k(x + -4) Reorder the terms: -15 + 2x + 2x = k(x + -4) Combine like terms: 2x + 2x = 4x -15 + 4x = k(x + -4) Reorder the terms: -15 + 4x = k(-4 + x) -15 + 4x = (-4 * k + x * k) -15 + 4x = (-4k + kx) Solving -15 + 4x = -4k + kx Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1kx' to each side of the equation. -15 + -1kx + 4x = -4k + kx + -1kx Combine like terms: kx + -1kx = 0 -15 + -1kx + 4x = -4k + 0 -15 + -1kx + 4x = -4k Add '15' to each side of the equation. -15 + -1kx + 15 + 4x = 15 + -4k Reorder the terms: -15 + 15 + -1kx + 4x = 15 + -4k Combine like terms: -15 + 15 = 0 0 + -1kx + 4x = 15 + -4k -1kx + 4x = 15 + -4k Reorder the terms: -15 + 4k + -1kx + 4x = 15 + -4k + -15 + 4k Reorder the terms: -15 + 4k + -1kx + 4x = 15 + -15 + -4k + 4k Combine like terms: 15 + -15 = 0 -15 + 4k + -1kx + 4x = 0 + -4k + 4k -15 + 4k + -1kx + 4x = -4k + 4k Combine like terms: -4k + 4k = 0 -15 + 4k + -1kx + 4x = 0 The solution to this equation could not be determined.
