By using the Distributive Property, you would multiply 3 into the parenthesis (3 · x and 3 · -4)
3(x - 4) = 24
3x - 12 = 24
Then, you would solve like any normal one-step equation.
3x - 12 = 24
+12 +12
__________
3x 36
__ = __
3 3
x = 12, which is your final solution.

Answer:
1) Angle L = angle J : Given
2) Line KJ || line LM: Given
3) angle KML = KMJ: They are alternate interior angles
4) 180 - angle L - angle KLM = angle LKM
180 - angle J - angle KJM = angle JMK
5) because you know two angles of triangle, you know the third. Because angle L = angle J and angle KLM = angle angle KJM, then the remaining angle LKM must equal the remaining angle JMK
