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 - 7a = 4a + 8y - 3 for a in terms of y.
| y + \(\frac{3}{13}\) | |
| \(\frac{3}{5}\)y + \(\frac{3}{10}\) | |
| -\(\frac{1}{3}\)y + 2 | |
| 15y - 3 |
