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 - b = -8b + 7y - 7 for b in terms of y.
| \(\frac{8}{13}\)y - \(\frac{7}{13}\) | |
| -\(\frac{8}{11}\)y - \(\frac{2}{11}\) | |
| 3\(\frac{1}{5}\)y - \(\frac{3}{5}\) | |
| -\(\frac{1}{3}\)y + 1\(\frac{2}{3}\) |
