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 c + 9c = -3c - 8y + 7 for c in terms of y.
| \(\frac{7}{11}\)y + \(\frac{6}{11}\) | |
| -4\(\frac{1}{4}\)y + 1\(\frac{3}{4}\) | |
| -y + \(\frac{1}{9}\) | |
| \(\frac{1}{4}\)y - \(\frac{3}{4}\) |
