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