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 4c + 4c = 8c + 3y - 7 for c in terms of y.
| -2y + 2\(\frac{2}{3}\) | |
| \(\frac{3}{11}\)y + \(\frac{1}{11}\) | |
| -2y - \(\frac{1}{4}\) | |
| \(\frac{1}{4}\)y + 1\(\frac{3}{4}\) |
