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 - 7a = -6a + 5x + 4 for a in terms of x.
| -\(\frac{2}{11}\)x + \(\frac{9}{11}\) | |
| -6x - 2 | |
| -9x + 3 | |
| 3\(\frac{1}{3}\)x + \(\frac{2}{3}\) |
