Answer:
1) Subtracting one from the other
2) x = 0.375 and y = 0.125
Step-by-step explanation:
Equation 1 :

Equation 2:

To solve these equations by the Elimination method we multiply equation 1 with 6 and multiply equation 2 with 2 so now,

Now for the second equation:

Now subtracting equation 2 from equation 1

now insert this value of y into any equation
lets insert it into equation 1

Answer:
250 Rs.
Step-by-step explanation:
600 / 12 x 5 = 250 Rs.
Ram will get 250 Rs.
A pound of oranges cost x dollar => A pound of pears cost x+3 dollar
We have: 8x+4(x+3)=30 => 12x=30-12=18 =>x=1.5
5 pounds of pears cost: 5(x+3)=5(1.5+3)=5*4.5= 22.5 (dollar)
