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 4b + 3b = 9b + 8y - 5 for b in terms of y.
| y + 2\(\frac{2}{3}\) | |
| 1\(\frac{1}{5}\)y + 1\(\frac{4}{5}\) | |
| -10y - 4 | |
| -y + 1 |
