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