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