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 3a - 7a = 6a - 8z + 1 for a in terms of z.
| \(\frac{7}{12}\)z + \(\frac{1}{4}\) | |
| z + \(\frac{9}{10}\) | |
| \(\frac{1}{3}\)z - \(\frac{1}{3}\) | |
| \(\frac{1}{5}\)z + \(\frac{1}{5}\) |
