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 -5a + 3a = 8a - 8y + 7 for a in terms of y.
| \(\frac{11}{13}\)y - \(\frac{7}{13}\) | |
| -y + 3 | |
| y + \(\frac{4}{5}\) | |
| -2\(\frac{1}{6}\)y + \(\frac{1}{6}\) |
