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