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 = 8a + y - 2 for a in terms of y.
| -\(\frac{1}{14}\)y - \(\frac{3}{7}\) | |
| y + \(\frac{2}{15}\) | |
| -1\(\frac{3}{4}\)y - 1\(\frac{1}{4}\) | |
| -6y - 7 |
