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