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 3a - 6a = 7a + 9x + 3 for a in terms of x.
| -3\(\frac{3}{4}\)x - \(\frac{3}{4}\) | |
| -8x - 8 | |
| \(\frac{2}{7}\)x - 1 | |
| -\(\frac{3}{14}\)x - \(\frac{1}{14}\) |
