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 -3c + 5c = -5c - 7x + 7 for c in terms of x.
| -4x + 2\(\frac{2}{3}\) | |
| 3x + 1 | |
| \(\frac{5}{7}\)x + \(\frac{4}{7}\) | |
| -6x + 3\(\frac{1}{2}\) |
