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 -8a + 6a = 4a - 5z + 6 for a in terms of z.
| -1\(\frac{1}{2}\)z + \(\frac{1}{4}\) | |
| 4z - 1 | |
| \(\frac{11}{12}\)z - \(\frac{1}{2}\) | |
| \(\frac{7}{16}\)z + \(\frac{1}{8}\) |
