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 -2b - 5b = 6b - 9z + 7 for b in terms of z.
| \(\frac{1}{2}\)z - \(\frac{7}{8}\) | |
| \(\frac{1}{6}\)z - \(\frac{3}{4}\) | |
| 9z + 2 | |
| \(\frac{2}{17}\)z + \(\frac{7}{17}\) |
