Question

Find for what value of s and g the system has
i. A unique solution
ii. No Solution
iii. Infinitely many solution

x+4y+2z=1
2x+7y+5z=2s
4x+gy+10z=2s+1

​

Answer 1

It has no solution

hope it helps

Answer 2

Answer:

Infinitely many solutions

Step-by-step explanation:

in second equation for every value of X and y there is a corresponding value of 's'.

and in third equation for every value of x,y,g, and z there is corresponding value of 's'

like that it also happens with 'g'.
