Answer 1

Answer:

Helo guy's

here, / is upon

Step-by-step explanation:

The step by step explanation ,

Here , a=7 and b=3 ,

the given equations are :

2x - ( a - 4)y = 2b + 1

and 4x - (a - 1)y = 5b + 1

therefore , a1 = 2, a2 = 4 , b1 = - ( a - 4 )

b2 = - ( a- 1) , c1 = 2b + 1 , c2 = 5b - 1

since it is given that the system of linear equation have infinite many solutions therefore,

a1/a2 = b1/b2 = c1/c2

2/4 = -(a-4)/-(a-1) = 2b + 1/ 5b +1

a-4/a-1 = 2/4 , 2b+1 /5b-1 = 2/4

2a -8 =a -1 , 4b +2 = 5b -1

a = 7 and b = 3 .

Hope it will help you out guys .
