Hiya!
x is going to work out to 25.
———————————————
so first put the numbers into the equation you’ve been given.
pressure is 3, force is 1500 so 3=1500/area
then rearrange this equation so that you’re finding area.
area=1500/3
and 1500/3 gives you 500.
so 500 is the area.
area is length multiplied by width, so 20 multiplied by x.
total/width will give length, so 500/20 will give x.
500/20=25
so x is 25.
The answer is y= -3
Hope this help
