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