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 -8a + 3a = 5a - 5x + 3 for a in terms of x.
| x + \(\frac{2}{7}\) | |
| \(\frac{6}{7}\)x - \(\frac{6}{7}\) | |
| -\(\frac{6}{7}\)x - \(\frac{5}{7}\) | |
| \(\frac{8}{13}\)x - \(\frac{3}{13}\) |
