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 + 2a = -4a - 6x + 1 for a in terms of x.
| \(\frac{4}{9}\)x + \(\frac{1}{3}\) | |
| 1\(\frac{3}{4}\)x + \(\frac{1}{2}\) | |
| 2\(\frac{2}{3}\)x - \(\frac{1}{3}\) | |
| \(\frac{3}{13}\)x - \(\frac{5}{13}\) |
