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 7c + 9c = -8c + 4x + 7 for c in terms of x.
| 4x + 1 | |
| \(\frac{9}{13}\)x - \(\frac{3}{13}\) | |
| -1\(\frac{1}{14}\)x + \(\frac{1}{7}\) | |
| -\(\frac{1}{3}\)x + \(\frac{7}{15}\) |
