Question

(iv) 0.2x +0.3y=1.3
0.4x +0.5y=2.3 by substition method​

Answer 1

Step-by-step explanation:

first you need to multiply the first term and second term with 10 because of point in it

then the value would be

2x+3y=13

4x+5y=23

after that

x= 13-3y/2 because of substitution

then place the value of 2nd one in it

4(13-3y)/2 + 5y = 23 this will come after placing it

then solve it your answer will be there

then place the value of y in 1st or in 2nd term

for your solution then solve it your answer will be there.
