Ответ:
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
Ответ:
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.
Ответ:
B
