When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -8b - 9b = -2b + 2z - 1 for b in terms of z.
| \(\frac{1}{4}\)z + \(\frac{3}{4}\) | |
| -\(\frac{7}{9}\)z - \(\frac{2}{9}\) | |
| -1\(\frac{5}{6}\)z + \(\frac{1}{6}\) | |
| -1\(\frac{1}{2}\)z - 1\(\frac{1}{3}\) |
