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 6a - 5a = -2a - 2z + 4 for a in terms of z.
| \(\frac{2}{3}\)z + \(\frac{2}{9}\) | |
| \(\frac{3}{8}\)z + \(\frac{1}{2}\) | |
| 1\(\frac{2}{7}\)z + \(\frac{2}{7}\) | |
| \(\frac{1}{13}\)z + \(\frac{1}{13}\) |
