X=20 is the solution to 4=x-16

True

Step-by-step explanation:

So let's put this question into one equation.

x - 16 = 4 if x = 20

Well, this is a true statement. If we were to replace x with 20. We would see that the equation makes sense.

20 - 16 = 4

20 minus 16 does indeed equal 4.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
