Step-by-step explanation:
so first you combine like terms , 3x-x-4=4 turns into 4x-4=4 then u add 4 to both sides [inverse operations]
4x-4=4
+4 +4
--------------
4x= 8
----------
4. 4
×=2
then u use inverse operations. agian and divide 4 into 8 and you get 2 !! x = 2
Answer:
x = 4
Step-by-step\ explanation:
4 = 3x -x -4
+4 +4 - cancel out
8 = 3x -x (3x -x = 2x)
8 = 2x
divide
2x divided by 8 = 4(answer)
