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 a + 3a = -6a + 2x + 8 for a in terms of x.
| -\(\frac{1}{7}\)x + 1\(\frac{1}{7}\) | |
| -5x + 1\(\frac{1}{3}\) | |
| -\(\frac{4}{17}\)x - \(\frac{2}{17}\) | |
| \(\frac{3}{5}\)x + \(\frac{7}{10}\) |
