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 = 8a - 4y + 5 for a in terms of y.
| \(\frac{3}{7}\)y - 1\(\frac{2}{7}\) | |
| -3y - 8 | |
| y - 1 | |
| \(\frac{1}{6}\)y - \(\frac{5}{12}\) |
