Question 1044068
To check your answer, plug your solution into your initial equations.
.
.
How did you get your first equation?
Also, the right hand side of the second equation should be 35.
x-cost of 1 kg of potatoes
y-cost of 1 kg of onions
The cost of 8 kg of onions is rs-46.
1.{{{8y=46}}}
The cost of 10 kg of potatoes and 5 kg of onions is rs-35
2.{{{10x+5y=35}}}
Divide both side by 5.
{{{2x+y=7}}}
From eq. 1,
{{{y=46/8}}}
{{{y=23/4}}}
So then substituting,
{{{2x+23/4=7}}}
{{{2x=28/4-23/4}}}
{{{2x=5/4}}}
{{{x=5/8}}}
So then verifying using eq. 2,
{{{10(5/8)+5(23/4)=35}}}
{{{25/4+115/4=35}}}
{{{140/4=35}}}
{{{35=35}}}
True, so you have a good solution.
{{{x=0.625}}}
{{{y=5.75}}}
