Simplifying abs(x + 4) + abs(x + -7) = abs(2x + -1) Reorder the terms: abs(4 + x) + abs(x + -7) = abs(2x + -1) (4 * abs + x * abs) + abs(x + -7) = abs(2x + -1) (4abs + absx) + abs(x + -7) = abs(2x + -1) Reorder the terms: 4abs + absx + abs(-7 + x) = abs(2x + -1) 4abs + absx + (-7 * abs + x * abs) = abs(2x + -1) 4abs + absx + (-7abs + absx) = abs(2x + -1) Reorder the terms: 4abs + -7abs + absx + absx = abs(2x + -1) Combine like terms: 4abs + -7abs = -3abs -3abs + absx + absx = abs(2x + -1) Combine like terms: absx + absx = 2absx -3abs + 2absx = abs(2x + -1) Reorder the terms: -3abs + 2absx = abs(-1 + 2x) -3abs + 2absx = (-1 * abs + 2x * abs) -3abs + 2absx = (-1abs + 2absx) Add '-2absx' to each side of the equation. -3abs + 2absx + -2absx = -1abs + 2absx + -2absx Combine like terms: 2absx + -2absx = 0 -3abs + 0 = -1abs + 2absx + -2absx -3abs = -1abs + 2absx + -2absx Combine like terms: 2absx + -2absx = 0 -3abs = -1abs + 0 -3abs = -1abs Solving -3abs = -1abs Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add 'abs' to each side of the equation. -3abs + abs = -1abs + abs Combine like terms: -3abs + abs = -2abs -2abs = -1abs + abs Combine like terms: -1abs + abs = 0 -2abs = 0 Divide each side by '-2'. abs = 0 Simplifying abs = 0 The solution to this equation could not be determined.
