1) 9×2×c = 36018c = 360c = 360 ÷ 18c = 20
2) 120÷a = 48 ÷ 24a = 120 ÷ 48 ÷ 24a = 5
3) 740 + y = 1000 - 50740 + y = 950y = 950 - 740y = 210
Итак, решение уравнений:c = 20a = 5y = 210
1) 9×2×c = 360
18c = 360
c = 360 ÷ 18
c = 20
2) 120÷a = 48 ÷ 24
a = 120 ÷ 48 ÷ 24
a = 5
3) 740 + y = 1000 - 50
740 + y = 950
y = 950 - 740
y = 210
Итак, решение уравнений:
c = 20
a = 5
y = 210
