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 + c = 7c - 2z + 6 for c in terms of z.
| -\(\frac{1}{3}\)z + \(\frac{1}{3}\) | |
| z + \(\frac{3}{4}\) | |
| \(\frac{3}{11}\)z - \(\frac{6}{11}\) | |
| -1\(\frac{1}{8}\)z - 1\(\frac{1}{8}\) |
