You're welcome
First you want to get x by it’s self so you need to get ride of your 5 so you subtract 5 on both sides leaving you with -2 and -5 on the same side then you combine those two number to get -7 now to get your x all you have to do is divide both sides by -7 since your x is -7 once once your x is now by its self but on the other side -7 divided by -7 equals 1 bc 7 goes into 7 once and it turns positive because anytime you divide an negative number by a negative number it turns into a positive number so your answer over all is 1=x
The two triangles are similar.
40/x = 32/4
x = 5
