Question

Simultaneous equation​

Answer 1

Answer:

1/6 & 1

Step-by-step explanation:

Let 1/x be a and 1/y be b

Substituting values

2a - 3b =15 ----(1)

8a +5b =77----(2)

Multiplying eq (1) by 4 to get same coefficient

4(2a - 3b =15)

--> 8a -12b=60---(3)

Subtracting (3)&(2)

b=1

Now putting b in eq (1)

a=6

so 1/x= a

x=1/a=1/6

1/y= b

y=1/b=1/1=1
