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 + 8b = 3b - 5y - 1 for b in terms of y.
| -16y + 5 | |
| 1\(\frac{1}{10}\)y + \(\frac{3}{10}\) | |
| -13y - 1 | |
| 1\(\frac{1}{5}\)y + \(\frac{7}{10}\) |
