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