Question

Add this simultaneous equation by Elimination Method ​

Answer 1

Answer:

Step-by-step explanation:

Let x+y=a

x-y=b

Then,3/a+2/b=2

a/3+b/2=1/2

Multiplying both sides by 6 so we get,

2a+3b=1/3...........i

9/a+4/b=1

a/9+b/4=1

Multiplying both sides by 24 we get,

4a-9b=1/24..........ii

Multiplying equation i by 2 then subtracting equation i from ii

4a-9b=1/24

4a+6b=1/6

(-) (-) (-)

-15b=-3/24

b=1/8×1/15

=1/120
