x + y = 5
0.1(x) + 0.25(y) = 0.2 (5)

Question

x + y = 5  
0.1(x) + 0.25(y) = 0.2 (5)

anonymous · Answer

multiply both the equations with 100
in the first step @snsd9

anonymous · Answer

@snsd9  are you done with this step or not.. ?? or should i write down all the steps.. ?

anonymous · Answer

yes please

anonymous · Answer

That would help me a lot.

anonymous · Answer

just try solving the question here in the comments side by side that would let you understand much better
so , to start with multiply both the equations with 100
i.e. 100 ( x + y ) = 100 (5)
and the other 100(0.1(x) + 0.25(y)) = 0.2 (5) (100)

Thank you
Then then solve for x and y right?

anonymous · Answer

yeah from either of the equation get the equation to find out any of the x or y 
and then put that value in the other equation to get the values
