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 -7b + 9b = 4b - 3z + 3 for b in terms of z.
| -\(\frac{4}{9}\)z + \(\frac{8}{9}\) | |
| 1\(\frac{1}{11}\)z - \(\frac{3}{11}\) | |
| \(\frac{1}{11}\)z - \(\frac{5}{11}\) | |
| z - 9 |
