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 -7b - 8b = -3b + 6z - 7 for b in terms of z.
| 1\(\frac{2}{7}\)z + 1\(\frac{1}{7}\) | |
| -\(\frac{3}{5}\)z - \(\frac{1}{2}\) | |
| -3\(\frac{1}{2}\)z + 1\(\frac{3}{4}\) | |
| -\(\frac{8}{11}\)z + \(\frac{6}{11}\) |
