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 a + 9a = 4a - 6y - 5 for a in terms of y.
| -\(\frac{2}{3}\)y - \(\frac{2}{3}\) | |
| -1\(\frac{1}{2}\)y + 3 | |
| -\(\frac{1}{10}\)y + \(\frac{3}{5}\) | |
| 5y + 1\(\frac{2}{3}\) |
