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 = -9b + 3z + 7 for b in terms of z.
| \(\frac{2}{3}\)z + \(\frac{2}{3}\) | |
| 2\(\frac{3}{4}\)z + 1\(\frac{3}{4}\) | |
| \(\frac{3}{4}\)z - \(\frac{3}{4}\) | |
| 12z - 9 |
