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 + 3c = -8c + 3z + 7 for c in terms of z.
| -\(\frac{3}{11}\)z + \(\frac{9}{11}\) | |
| z + 2\(\frac{2}{3}\) | |
| z + 1\(\frac{3}{4}\) | |
| -\(\frac{3}{4}\)z + \(\frac{1}{8}\) |
