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