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 -a + 6a = 4a + 7y - 2 for a in terms of y.
| -\(\frac{1}{5}\)y + \(\frac{2}{5}\) | |
| y - 1 | |
| \(\frac{2}{5}\)y - \(\frac{1}{5}\) | |
| -\(\frac{4}{7}\)y - 1\(\frac{1}{7}\) |
