R=2K which equals 2R=4K
4(R=K+8) or 4R=4K+32
Subtract first equation from second equation.
2R=32 so R=16
Plug into first equation
16=2K so K=8
Now plug both into second equation to check
4R-4K=4(R-K)=4(8)=32 it works
So Roberto is 16 and Katie is 8
(In 4 years R would be 20 and K would be 12 which has a difference of 8)
Hello :
an equation is : y-5 = 0(x-3)....<span> perpendicular to the line x=4 ( parrallel to x-axis)
so ;
</span>y=5
