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 + c = -3c + 8y + 7 for c in terms of y.
-\(\frac{7}{15}\)y - \(\frac{2}{15}\) | |
1\(\frac{1}{2}\)y - \(\frac{1}{2}\) | |
y - \(\frac{2}{5}\) | |
1\(\frac{2}{5}\)y + 1\(\frac{2}{5}\) |
