Question

Помогите пожалуйста!​

Answer 1

Пошаговое объяснение:

A = 150

B = 23

$4a + b = 150 \times 4 + 23 = 623$

a - 2b = 150 - 23 • 2 = 150 - 46 = 104

A = 38

B = 19

$4a + b = 4 \times 38 + 19 = 152 + 19 = 171$

$a - 2b = 38 - 19 \times 2 = 38 - 38 = 0$

A = 72

B = 9

$4a + b = 4 \times 72 + 9 = 288 + 9 = 297$

$a - 2b = 72 - 2 \times 9 = 72 - 18 = 54$
