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 + 9a = 5a - 8x + 1 for a in terms of x.
| -17x + 1 | |
| -1\(\frac{3}{4}\)x - 1\(\frac{1}{4}\) | |
| -1\(\frac{7}{9}\)x + \(\frac{4}{9}\) | |
| -\(\frac{11}{16}\)x - \(\frac{7}{16}\) |
