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