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 -4b - 8b = -9b - 8y - 2 for b in terms of y.
| -3y + 3 | |
| \(\frac{1}{4}\)y - 1\(\frac{1}{4}\) | |
| y - \(\frac{2}{5}\) | |
| \(\frac{11}{15}\)y - \(\frac{1}{5}\) |
