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