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 + 8c = 6c - 5z + 3 for c in terms of z.
| z - \(\frac{3}{7}\) | |
| -\(\frac{1}{4}\)z - \(\frac{1}{2}\) | |
| -1\(\frac{2}{7}\)z + 1\(\frac{2}{7}\) | |
| 1\(\frac{3}{10}\)z - \(\frac{3}{10}\) |
