Answer 1

Răspuns:

2x+3=-7

2x = -7-3 = -10

x = -10/2 = -5

7-2x= -23-12x

7+23= -12x+2x

30=-10x

x=30/-10 = -3

3(x-1)=-6

3x-3=-6

3x=-6+3

3x=-3

×=-1

2(x+2)=3x-6

2x+2=3x-6

6+2=3x-2x

8=x=8

4x+2=3(x+1)

4x+2=3x+3

4x-3x=3-2

x=1

8x-16=0

8x=0+16

8x=16

x=16/8=2

-4x+2=-30

-4x=-30-2

-4x=-32

x=-32/-4=8

2x+1=10-x

2x+x=10-1

3x=9

x=3

1-4(2x-1)=3(x+2)+10

1-8x+4=3x+6+10

1+4-6-10=3x+8x

-11=11x

x=-1

3-5(2x-1)=4(x+2)+14

3-10x+5=4x+8+14

3+5-8-14=4x+10x

-14=14x

x=-1
