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 + 2a = 7a - 7y + 6 for a in terms of y.
| \(\frac{9}{14}\)y - \(\frac{3}{7}\) | |
| \(\frac{1}{5}\)y + 1\(\frac{3}{5}\) | |
| 2y + 4 | |
| -\(\frac{14}{15}\)y + \(\frac{7}{15}\) |
