Step-by-step explanation:
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:
15, 17, 19, and 21
Step-by-step explanation:
make the equation
x+x+2+x+4+x+6=72
simplify
4x+12=72
x+3=18
x=15
