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