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 4a - 2a = -7a + 8y + 2 for a in terms of y.
| \(\frac{10}{11}\)y + \(\frac{2}{11}\) | |
| -2y - 1 | |
| -2y + 1 | |
| 1\(\frac{6}{7}\)y + 1\(\frac{1}{7}\) |
