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 -2c + 2c = 3c - y + 7 for c in terms of y.
| -\(\frac{3}{11}\)y + \(\frac{1}{11}\) | |
| -\(\frac{1}{2}\)y - 4 | |
| \(\frac{3}{5}\)y - 1\(\frac{2}{5}\) | |
| -10y + 9 |
