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 = -5b - 8z - 8 for b in terms of z.
| -z + \(\frac{4}{9}\) | |
| \(\frac{2}{13}\)z - \(\frac{4}{13}\) | |
| -2\(\frac{1}{7}\)z - 1\(\frac{1}{7}\) | |
| \(\frac{11}{18}\)z + \(\frac{1}{6}\) |
