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 - 7b = -7b - 6z - 7 for b in terms of z.
| \(\frac{1}{5}\)z - 1\(\frac{2}{5}\) | |
| -3\(\frac{1}{3}\)z + \(\frac{2}{3}\) | |
| 1\(\frac{2}{3}\)z - \(\frac{8}{9}\) | |
| -11z - 5 |
