Simplifying -1(z + 7) + (2z + 1) = -5(z + 1) Reorder the terms: -1(7 + z) + (2z + 1) = -5(z + 1) (7 * -1 + z * -1) + (2z + 1) = -5(z + 1) (-7 + -1z) + (2z + 1) = -5(z + 1) Reorder the terms: -7 + -1z + (1 + 2z) = -5(z + 1) Remove parenthesis around (1 + 2z) -7 + -1z + 1 + 2z = -5(z + 1) Reorder the terms: -7 + 1 + -1z + 2z = -5(z + 1) Combine like terms: -7 + 1 = -6 -6 + -1z + 2z = -5(z + 1) Combine like terms: -1z + 2z = 1z -6 + 1z = -5(z + 1) Reorder the terms: -6 + 1z = -5(1 + z) -6 + 1z = (1 * -5 + z * -5) -6 + 1z = (-5 + -5z) Solving -6 + 1z = -5 + -5z Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '5z' to each side of the equation. -6 + 1z + 5z = -5 + -5z + 5z Combine like terms: 1z + 5z = 6z -6 + 6z = -5 + -5z + 5z Combine like terms: -5z + 5z = 0 -6 + 6z = -5 + 0 -6 + 6z = -5 Add '6' to each side of the equation. -6 + 6 + 6z = -5 + 6 Combine like terms: -6 + 6 = 0 0 + 6z = -5 + 6 6z = -5 + 6 Combine like terms: -5 + 6 = 1 6z = 1 Divide each side by '6'. z = 0.1666666667 Simplifying z = 0.1666666667
