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 + 8b = 4b + 5y + 5 for b in terms of y.
| 2\(\frac{1}{2}\)y + 4 | |
| \(\frac{3}{11}\)y - \(\frac{5}{11}\) | |
| -1\(\frac{3}{5}\)y + \(\frac{3}{5}\) | |
| 1\(\frac{4}{5}\)y + \(\frac{1}{5}\) |
