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