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 - 3b = -8b - 7y + 9 for b in terms of y.
| -y - \(\frac{2}{3}\) | |
| 8y + 4 | |
| y + 1\(\frac{1}{8}\) | |
| -\(\frac{2}{3}\)y + 1\(\frac{1}{2}\) |
