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