Question

Given that 3 x minus 4 Y is equal to 7 and X + C Y is equal to 13 then for what value of C will the two equation have not have a solution

Answer 1

Answer:

for no solution we must have a1/a2=b1/b2 not equal to c1/c2

Step-by-step explanation:

3x-4y=7 x+cy=13

a1= 3

a2=1

b1= -4

b2= c

c1=7

c2=13

3/1=-4/cnot equal to 7/13

3c=-4

c=-4/3

And 7c us not equal to -52

so c is not equal to -52/7
