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 -6b - 6b = 5b + 3y + 7 for b in terms of y.
| 3y + 4 | |
| -2\(\frac{1}{2}\)y - 2\(\frac{1}{2}\) | |
| -1\(\frac{7}{12}\)y + \(\frac{1}{6}\) | |
| -\(\frac{9}{11}\)y - \(\frac{7}{11}\) |
