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