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 + 5c = 3c - 6y + 5 for c in terms of y.
| y + 1 | |
| -1\(\frac{2}{7}\)y + \(\frac{3}{7}\) | |
| 11y - 5 | |
| -\(\frac{5}{11}\)y - \(\frac{2}{11}\) |
