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 3a + 5a = 4a + 8y - 7 for a in terms of y.
| -\(\frac{6}{11}\)y + \(\frac{6}{11}\) | |
| -3y + 7 | |
| \(\frac{4}{7}\)y + \(\frac{5}{7}\) | |
| y - 7 |
