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 3b + 6b = -5b - 4y + 7 for b in terms of y.
| -7\(\frac{1}{2}\)y + 2\(\frac{1}{2}\) | |
| -1\(\frac{1}{4}\)y + \(\frac{7}{8}\) | |
| y - \(\frac{1}{3}\) | |
| -y - 3 |
