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 -4c - 6c = -c - 9z - 5 for c in terms of z.
| \(\frac{3}{7}\)z - \(\frac{2}{7}\) | |
| 7z - 4 | |
| \(\frac{5}{17}\)z + \(\frac{5}{17}\) | |
| z + 1\(\frac{2}{3}\) |
