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 + 9a = 7a + x + 3 for a in terms of x.
| -\(\frac{6}{13}\)x - \(\frac{6}{13}\) | |
| \(\frac{2}{3}\)x - \(\frac{1}{4}\) | |
| \(\frac{1}{11}\)x - \(\frac{3}{11}\) | |
| -16x - 8 |
