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 + 6a = -8a + 7x - 2 for a in terms of x.
| x + 3 | |
| \(\frac{7}{9}\)x - \(\frac{2}{3}\) | |
| \(\frac{1}{3}\)x - \(\frac{1}{3}\) | |
| \(\frac{1}{3}\)x - \(\frac{2}{3}\) |
