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 - 8a = -5a - 7z - 2 for a in terms of z.
| -\(\frac{3}{14}\)z + \(\frac{1}{14}\) | |
| -10z + 5 | |
| -z + 2 | |
| -1\(\frac{3}{5}\)z + \(\frac{4}{5}\) |
