Question

Решите уравнение:

1) -9х =0

2) -16х +64=0

3) +12х +72=0

Answer 1

Решение и ответ:

1) -9x = 0

x = 0 ÷ (-9)

x = 0

2) -16х + 64 = 0

-16x = -64

x = -64 ÷ (-16)

x = 4

3) 12x + 72 = 0

12x = -72

x = -72 ÷ 12

x = -6

Answer 2

-9х=0
х=0/(-9)
х=0

-16х+64=0
-16х=-64
х=4

12х+72=0
12х=-72
х=-6
