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 + 6b = -4b - 2z - 5 for b in terms of z.
| 6z + 4\(\frac{1}{2}\) | |
| -\(\frac{9}{11}\)z + \(\frac{6}{11}\) | |
| -1\(\frac{1}{3}\)z - \(\frac{5}{6}\) | |
| \(\frac{13}{15}\)z - \(\frac{1}{5}\) |
