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 - 2b = -7b + 5z - 9 for b in terms of z.
| -\(\frac{2}{3}\)z + 1 | |
| \(\frac{7}{15}\)z - \(\frac{3}{5}\) | |
| 3z + \(\frac{4}{5}\) | |
| -\(\frac{3}{7}\)z - \(\frac{3}{7}\) |
