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