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”.
pls ans it as soon as possible​

Answer 1

Step-by-step explanation:

Given,

x=-2

y=6

3ax+2ay=6

3a(-2)+2a(6)=6

-6a+12a=6

6a=6

a=1

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

2a-2+4b-8=4

2a+4b-10=4

2a+4b=4+10

2(1)+4b=14

2+4b=14

4b=14-2

4b=12

b=12/4

b=3

a=1, b=3
