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 - b = -8b - 5y + 9 for b in terms of y.
| -y - \(\frac{1}{9}\) | |
| -13y + 4 | |
| -1\(\frac{3}{4}\)y + 2 | |
| -y + 2\(\frac{1}{4}\) |
