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