Question

The difference between two numbers is 5. If the smaller is doubled, the result will be two less than the larger. Find the numbers?? I need HELP please :/

Answer 1

Lets say x is the bigger number and y is the smaller number
x-y=5
2y=x-2
Now simultaneously solve them.

Answer 2

I am followingg off what williamnz said. Add y to both sides of the first equation to get x by itself and substitute x in the second equation.

Answer 3

You can either use the substitution or elimination method. I'll show you the elimination one
x-y=5
x-2y=2
Eliminate x
-y-(-2y)=5-2
y=5-2
y=3
Now to find x we input y into one of the equations
x-3=5
x=5+3
x=8
So the numbers are 3, 8

Answer 4

@williamnz i was actually just going to ask what method do i use but you answer my question thank you

Answer 5

no problem
