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 + a = 4a + 5y + 1 for a in terms of y.
| -\(\frac{1}{3}\)y + \(\frac{8}{9}\) | |
| -\(\frac{4}{11}\)y - \(\frac{1}{11}\) | |
| -1\(\frac{4}{9}\)y + \(\frac{1}{9}\) | |
| 2\(\frac{3}{7}\)y + \(\frac{6}{7}\) |
