Answer 1

Answer:

Your question is incopmlete bro

But i found u r question and here is u r answer

Step-by-step explanation:

Q- 0.4x+0.3y=1.7;0.7x-0.2y=0.8

Answer

First of all multiply both  equations by 10 to get 4x+3y=17(eq 1)

and

7x-2y=8(eq 2)

We will solve this question by substitution method

From eq 2 7x-2y=8

Transporting values

7x=8+2y

x=(8+2y)/7

Therefore we get x=8+2y/7

Now we will substitute value of x in eq1

4(8+2y/7)+3y=17

32+8y/7+3y=17

32+8y+21y/7=17..(taking LCM=7)

32+29y=17.7

29y=119-32

29y=87

y=3

Now substitute value of y in eq2 to get

7x-2(3)=8

7x-6=8

7x=8+6

x=2

I hope it will help u
