Answer:

Step-by-step explanation:

If you want to solve this easily, you can just remove x and add 30x + 60x.

We know that 30 + 60 is 90. So we will add x to 90.

Now you have your answer!
Hope this helps!
Answer:
EF=6
Step-by-step explanation:
E is the midpoint, so DE = EF
DE = 15-3x
EF = x+ 3
Since DE = EF,
15 - 3x = x + 3
-4x = -12
x = 3
If x = 3,
DE = 15 - 3*3, 15 - 9 = 6
EF = x+ 3, so EF = 3 + 3 = 6
