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 - 4b = 7b + 5y - 2 for b in terms of y.
| \(\frac{1}{3}\)y - \(\frac{1}{3}\) | |
| 5\(\frac{1}{2}\)y + \(\frac{1}{2}\) | |
| \(\frac{15}{16}\)y - \(\frac{1}{2}\) | |
| -\(\frac{3}{4}\)y + \(\frac{1}{6}\) |
