Question

Can someone help me please?

Answer 1

X=7 hope this helped

Answer 2

x=7

Explanation:

All you have to do is take just two of the sides and just say that they're equal, find x and then plug it in to see if it works with all of them. So we have:

`7x - 19 = 4x + 2 \\ 7x - 4x = 19 + 2 \\ 3x = 21 \\ x = (21)/(3 ) \\ x = 7`

Plug x into the other sides and you'll see that it checks out since you'll always get 30. Hope it helped :)
