Question

Ifx=-2 and y=6 is a solution of 3ax+2ay=6 then find “a” and then from 2(a-1)+2(2b-4)=4, find “b”.​

Answer 1

a= 1,b = 3

Step-by-step explanation:

–6a+12a = 6

a = 1

2(a–1)+2(2b-4) =4

4b–8 =4 ( a=1)

4b = 12

b = 3

Answer 2

Step-by-step explanation:

Case 1,

3×a×(-2)+2×a×6=6

-6a+12a=6

6a=6

a=1

Case 2,

2(1-1)+2(2×b-4)=4

2×0+4b-8=4

0+4b=4-8

b=-4/4

b=-1
