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 + 10a = -8a - 9x + 4 for a in terms of x.
| \(\frac{1}{2}\)x - \(\frac{1}{2}\) | |
| -1\(\frac{8}{11}\)x + \(\frac{4}{11}\) | |
| -3\(\frac{1}{4}\)x + 1\(\frac{1}{4}\) | |
| -\(\frac{5}{9}\)x + \(\frac{1}{9}\) |
