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 + 8b = -b - 7z + 3 for b in terms of z.
| z + \(\frac{1}{3}\) | |
| 3\(\frac{3}{4}\)z - \(\frac{3}{4}\) | |
| z + 3 | |
| -9z - 2 |
