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 + 3c = 6c - 7z + 7 for c in terms of z.
| z - \(\frac{2}{3}\) | |
| -7z - 2 | |
| -10z - 2 | |
| -10z + 7 |
