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 9a + 7a = -7a + 2x + 5 for a in terms of x.
| -\(\frac{5}{16}\)x + \(\frac{5}{16}\) | |
| \(\frac{13}{17}\)x + \(\frac{6}{17}\) | |
| -1\(\frac{3}{4}\)x + 1\(\frac{3}{4}\) | |
| -5\(\frac{1}{2}\)x + 2\(\frac{1}{2}\) |
