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 - 4b = -3b - 8z + 7 for b in terms of z.
| -\(\frac{2}{3}\)z + \(\frac{5}{18}\) | |
| \(\frac{2}{3}\)z - 1\(\frac{1}{6}\) | |
| -z - \(\frac{2}{5}\) | |
| \(\frac{1}{11}\)z - \(\frac{9}{11}\) |
