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 + a = -8a + 4y - 1 for a in terms of y.
| \(\frac{11}{15}\)y - \(\frac{3}{5}\) | |
| 14y - 4 | |
| -1\(\frac{2}{9}\)y + \(\frac{7}{9}\) | |
| \(\frac{1}{5}\)y - \(\frac{1}{15}\) |
