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 -4a - 4a = 5a + 5x - 6 for a in terms of x.
| -\(\frac{2}{5}\)x - \(\frac{7}{15}\) | |
| -\(\frac{1}{3}\)x + 1\(\frac{1}{3}\) | |
| \(\frac{3}{10}\)x + \(\frac{7}{10}\) | |
| -x + \(\frac{2}{3}\) |
