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 + a = -4a + y - 6 for a in terms of y.
| 2\(\frac{1}{4}\)y + 1\(\frac{1}{2}\) | |
| 10y + 5 | |
| -2\(\frac{1}{2}\)y - 1 | |
| y + 2 |
