Answer:

A = 6, B = 1.

Step-by-step explanation:

3A + 2B = 20

2A + B = 13 Multiply this by -2:

-4A - 2B = -26 Add this equation to the first equation:

-A = -6

A = 6.

and from the second equation:

2(6) + B = 13

B = 13 - 12 = 1.

3A+2B=20

2A+B=13 ➡×(-2)➡-4A-2B=-26

3A+2B-4A-2B=20-26

-A=-6 ➡A=6

2(6)+B=13➡B=1
