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 9b - 7b = -6b - 8z - 7 for b in terms of z.
| 11z - 8 | |
| -\(\frac{1}{15}\)z - \(\frac{7}{15}\) | |
| -10z - 3 | |
| \(\frac{2}{5}\)z + \(\frac{7}{15}\) |
