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 = -6a + 7y - 3 for a in terms of y.
| -13y + 1 | |
| 1\(\frac{1}{5}\)y - 1 | |
| \(\frac{4}{7}\)y + 1\(\frac{1}{7}\) | |
| 1\(\frac{1}{12}\)y - \(\frac{1}{4}\) |
