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 -5b + 9b = 7b + 9z - 3 for b in terms of z.
| -6z + 4 | |
| -\(\frac{1}{15}\)z - \(\frac{3}{5}\) | |
| \(\frac{2}{11}\)z - \(\frac{7}{11}\) | |
| z + \(\frac{1}{4}\) |
