Hello :
x : length y :<span> width
</span>xy = 50 ...(1)
x = 2y ...(2)
dubsct in (1) :
(2y)(y) = 50
y² = 25
y = 5
x = 10
Answer:
answer: 5x + 10
Step-by-step explanation:
The distributive property (of which this is an example) demands that the 5 must multiply the x (which was done correctly) to give 5x
But the problem becomes undone when you forget about the 2. You must multiply the 2 by 5 as well to give 10.
The plus sign cannot be destroyed. The terms are not alike. So the answer is 5x + 10

Answer:
x = 1/8
Step-by-step explanation:
It seems like you already did most of the work. The last step is to just divide both sides by 8, to get rid of the 8 attached to the x.
so that should yield:
x = 1/8
