Answer:
x=3
Explanation:
15+17+5x = 47
if you add 15 and 17 just to make it easier, you get....
32+5x = 47
what I did next was minus 32 from each side.
so you are left with....
5x = 15
divide each side by 5 and you get
x = 3
you can go back and make sure that- that is right by doing 15+17=32 and
5x3 = 15 then add them together, 32+15 = 47
