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