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 + 8a = 3a + 8y - 6 for a in terms of y.
| y + \(\frac{3}{4}\) | |
| 3y - 1\(\frac{1}{3}\) | |
| \(\frac{2}{17}\)y - \(\frac{7}{17}\) | |
| -1\(\frac{7}{8}\)y - \(\frac{5}{8}\) |
