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 -6a - 8a = 5a + 7x + 4 for a in terms of x.
| x - \(\frac{1}{4}\) | |
| -2x + 1\(\frac{3}{5}\) | |
| -9x - 4 | |
| -1\(\frac{4}{11}\)x - \(\frac{4}{11}\) |
