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 -3c - 5c = -7c + 8y - 1 for c in terms of y.
-\(\frac{3}{10}\)y + \(\frac{3}{5}\) | |
-1\(\frac{4}{9}\)y - \(\frac{4}{9}\) | |
3\(\frac{1}{4}\)y - \(\frac{1}{4}\) | |
1\(\frac{1}{7}\)y + \(\frac{6}{7}\) |
