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 8a - 7a = -3a + 4y + 1 for a in terms of y.
| y + 2 | |
| \(\frac{6}{11}\)y - \(\frac{4}{11}\) | |
| y + \(\frac{1}{11}\) | |
| \(\frac{1}{3}\)y + \(\frac{1}{3}\) |
