Simplifying -1(z + -4) + (2z + 1) = -2(z + 1) Reorder the terms: -1(-4 + z) + (2z + 1) = -2(z + 1) (-4 * -1 + z * -1) + (2z + 1) = -2(z + 1) (4 + -1z) + (2z + 1) = -2(z + 1) Reorder the terms: 4 + -1z + (1 + 2z) = -2(z + 1) Remove parenthesis around (1 + 2z) 4 + -1z + 1 + 2z = -2(z + 1) Reorder the terms: 4 + 1 + -1z + 2z = -2(z + 1) Combine like terms: 4 + 1 = 5 5 + -1z + 2z = -2(z + 1) Combine like terms: -1z + 2z = 1z 5 + 1z = -2(z + 1) Reorder the terms: 5 + 1z = -2(1 + z) 5 + 1z = (1 * -2 + z * -2) 5 + 1z = (-2 + -2z) Solving 5 + 1z = -2 + -2z Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '2z' to each side of the equation. 5 + 1z + 2z = -2 + -2z + 2z Combine like terms: 1z + 2z = 3z 5 + 3z = -2 + -2z + 2z Combine like terms: -2z + 2z = 0 5 + 3z = -2 + 0 5 + 3z = -2 Add '-5' to each side of the equation. 5 + -5 + 3z = -2 + -5 Combine like terms: 5 + -5 = 0 0 + 3z = -2 + -5 3z = -2 + -5 Combine like terms: -2 + -5 = -7 3z = -7 Divide each side by '3'. z = -2.333333333 Simplifying z = -2.333333333
