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 - 5a = 3a - 2y + 6 for a in terms of y.
| -\(\frac{3}{10}\)y - \(\frac{3}{5}\) | |
| -y - 7 | |
| \(\frac{2}{15}\)y + \(\frac{8}{15}\) | |
| \(\frac{3}{4}\)y + \(\frac{5}{8}\) |
