Question

1) - 4+x=12
2)-4-x=-12
3) x-4 =-12
4) 4x= - 12
5) -4: x 12
6) x: (-4)= -12
7) 0,5x = − 0,3
9) 12(x + 5) = -24
10) 3(6-x)-2(x - 5) = 63​

Answer 1

Пошаговое объяснение:

1) -4 + x = 12

x = 12 + 4

x = 16

2) -4 - x = -12

x = -12 + 4

x = 8

3) x - 4 = -12

x = -12+4

x = -8

4) 4x = -12

x=-12/4

x = -3

5) -4 : x = 12

x=12/-4

x = -3

6) x : (-4) = -12

-(1/4)x=-12 - умножить обе части на -4

x = 48

7) 0.5x = -0.3

0.5x/0,5=-0,3/0,5

x = -0.6

8) 12(x + 5) = -24

x + 5 = -2

x=-2-5

x = -7

9) 3(6 - x) - 2(x - 5) = 63

18 - 3x - 2x + 10 = 63

-5x = 35

x = -7

Answer 2

Пошаговое объяснение:

х=16

х=8

х=-8

х=-3

х=?

х=-0,6

12х+60=-24

12х=-84

х=-7

18-3х-2х+10=63

-5х=35

х=-7
