Multiply both sides of the second equation by 4. That will give you -4x in the second equation which when added to 4x of the first equation will eliminate x.
Second equation:
-x + 3y = 6
Multiply the second equation by 4 on both sides:
-4x + 12y = 26
<span>1 and 2/3 time 1 and 1/3 is 2.22222222222 which rounds to 2.</span>
X is less then or equal to 1<u /><em /><u />
The perimeter is just the sum of all of the side lengths.
p=3x+4+x-10+5x-2
p=9x-8
