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 -4b + 5b = -3b - 8z + 9 for b in terms of z.
| 6z - 2\(\frac{1}{2}\) | |
| 13z - 9 | |
| \(\frac{5}{6}\)z - \(\frac{7}{12}\) | |
| -3\(\frac{3}{4}\)z - 2\(\frac{1}{4}\) |
