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 + 7c = 8c - 9y - 3 for c in terms of y.
2\(\frac{2}{7}\)y + \(\frac{3}{7}\) | |
-\(\frac{13}{17}\)y + \(\frac{1}{17}\) | |
-\(\frac{2}{7}\)y - \(\frac{1}{7}\) | |
1\(\frac{1}{3}\)y + \(\frac{4}{9}\) |
