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 = -6a - 2y - 1 for a in terms of y.
| \(\frac{3}{4}\)y + 1\(\frac{3}{4}\) | |
| -\(\frac{9}{13}\)y + \(\frac{9}{13}\) | |
| -\(\frac{3}{13}\)y - \(\frac{1}{13}\) | |
| -\(\frac{11}{12}\)y + \(\frac{7}{12}\) |
