Question

solve the linear equation by elimination method

(i) 3x-y=3
9x-3y=9

(ii) 0.2x + 0.3y=1.3
0.4x+0.5y=2.3

(iii) V2x+x3y=0
√3x - √8 y=0​

Answer 1

Answer:

1. 3x-y=7_________(I)

9x-3y=9_____________(ii)

by multiplying eq (I) by 3 :

3(3x-y)=7x3

9x-3y=21

by subtracting eq (ii) from eq(I)

9x-3y-(9x-3y)=21-9

0=12

this means this equation has no solution
