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 -2a + 3a = 2a + y - 4 for a in terms of y.
| -\(\frac{1}{11}\)y + \(\frac{4}{11}\) | |
| \(\frac{8}{9}\)y - \(\frac{8}{9}\) | |
| -7y - 4 | |
| \(\frac{1}{2}\)y + 1 |
