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 + 5a = -6a + y - 3 for a in terms of y.
| \(\frac{7}{13}\)y + \(\frac{6}{13}\) | |
| -\(\frac{4}{13}\)y - \(\frac{3}{13}\) | |
| 4y + 8 | |
| -2y - 2 |
