Answer:

(11,-23)

Step-by-step explanation:

3a+b=10 equation 1

-4a-2b=2 equation 2

using equation 1 we have

b = 10-3a equation 3

using equation 2 we have

-4a-2(10-3a)=2

-4a-20+6a=2

2a-20=2

2a=22

a=22/2

a=11

so using equation 3

we have

b = 10-3(11)= 10-33

b=-23

finally the answer is

(11,-23)
