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 + 9c = -5c - 4z + 6 for c in terms of z.
z - \(\frac{9}{10}\) | |
6\(\frac{1}{2}\)z - 3 | |
-9z - 3 | |
-3z - 6 |
