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 + c = 9c + y + 1 for c in terms of y.
| 1\(\frac{6}{7}\)y + 1 | |
| 1\(\frac{2}{7}\)y + 1 | |
| y - \(\frac{1}{16}\) | |
| y - 5 |
