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