Answer:
it has no solution
Step-by-step explanation:
first of all if we want to know that how many solutions does it the system we can know easly
- if a1/a2=b1/b2=c1/c2 then the system has infinite solution
- if a1/a2=b1/b2≠c1/c2 the system has no solution
- if a1/a2≠b1/b2 the system has no solution
so in this system a1=2,a2=4,b1=3,b2=6,c1=4&c2=4
so 2/4_3/6_4/4=(to becomfortable to compare we have to find the denominators LCM.LCM(4,6)=12
6/12=6/12≠12/12.
so the system has no solution.
&you can also solve by this way
2x+3y=4 (multiply by ‒2 to be y=0)
4x+6y=4
‒4x‒6y=‒8
4x+6y=4
= 0+0=‒4(error)
so it has no solution
i think it is clear & i hope it helps you.
Answer:
Each student; 32
Kevin; 12
Step-by-step explanation:
