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 -8a + 9a = 6a - 4y + 2 for a in terms of y.
| -y - \(\frac{2}{11}\) | |
| \(\frac{13}{14}\)y - \(\frac{1}{7}\) | |
| \(\frac{3}{10}\)y + \(\frac{1}{10}\) | |
| \(\frac{3}{8}\)y - \(\frac{3}{16}\) |
