Solve equation X/4-7=-3

This could mean two things from how you’ve written it.

It could mean there is an X with the denominator 4 or it could mean there’s an X with the denominator 4-7.

I am going to work with the first one and assume the 7 is separate. Apologies if that is incorrect.

First, I would add the 7 to both sides.

This leaves you with X/4 = 4

Then, multiply both sides by 4, to get X on its own.

This leaves X=16, which is the answer.

X=y+4 is the answe

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
