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 + 3b = -2b - 4y + 4 for b in terms of y.
| -2\(\frac{1}{2}\)y + \(\frac{1}{2}\) | |
| -y + \(\frac{4}{7}\) | |
| 7\(\frac{1}{2}\)y - 1\(\frac{1}{2}\) | |
| -15y - 1 |
