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 + 2b = -4b + y - 4 for b in terms of y.
| -6y - 2\(\frac{1}{2}\) | |
| y + 4 | |
| \(\frac{4}{5}\)y + \(\frac{3}{10}\) | |
| -3y + 6 |
