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