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