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 7a + a = -8a - 3x + 2 for a in terms of x.
| \(\frac{1}{4}\)x + 1\(\frac{1}{2}\) | |
| -\(\frac{4}{15}\)x + \(\frac{2}{15}\) | |
| \(\frac{1}{3}\)x - \(\frac{1}{3}\) | |
| -1\(\frac{1}{2}\)x + 2\(\frac{1}{4}\) |
