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 = 7b - y + 7 for b in terms of y.
| -\(\frac{8}{11}\)y + \(\frac{1}{11}\) | |
| \(\frac{2}{13}\)y - \(\frac{8}{13}\) | |
| 1\(\frac{1}{2}\)y - 3\(\frac{1}{2}\) | |
| \(\frac{1}{4}\)y - \(\frac{1}{8}\) |
