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 7a + 3a = 3a + 4y - 9 for a in terms of y.
| y - \(\frac{1}{3}\) | |
| -1\(\frac{1}{11}\)y - \(\frac{6}{11}\) | |
| 1\(\frac{2}{9}\)y + \(\frac{5}{9}\) | |
| \(\frac{1}{4}\)y - 2\(\frac{1}{4}\) |
