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 + 2a = 6a - 3y + 2 for a in terms of y.
| -\(\frac{3}{8}\)y - 1\(\frac{1}{8}\) | |
| -5y + 2 | |
| -\(\frac{11}{12}\)y + \(\frac{3}{4}\) | |
| \(\frac{1}{4}\)y + \(\frac{3}{4}\) |
