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 + a = 7a - 7z + 6 for a in terms of z.
| \(\frac{5}{11}\)z - \(\frac{7}{11}\) | |
| 2\(\frac{1}{5}\)z - 1 | |
| 8z - 6 | |
| \(\frac{1}{2}\)z + \(\frac{4}{5}\) |
