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 + 9a = -a + y - 2 for a in terms of y.
| \(\frac{10}{11}\)y + \(\frac{5}{11}\) | |
| \(\frac{1}{7}\)y - 1\(\frac{1}{7}\) | |
| -8y - 2 | |
| \(\frac{13}{16}\)y - \(\frac{9}{16}\) |
