Question

x/2 + y = 0.8 second equation 7/x + y/2 = 10 solve the equation in elimination method ​

Answer 1

Step-by-step explanation:

x+y=0.8______(I)

2

7+y=10__________(ii)

x 2

by multiplying (I) by 1/2 we get

1(X+y)=0.8x1/2

2 2

x+y=2/5

4 2

by subtracting (I) and (ii)

X/4+y/2-(7/X+y/2)=2/5-10

by this u can get ans
