Answer 1

Explicación paso a paso:

1.2x-7=-3

2×=7-3

2×=4

×=4/2=2

2.3×+5=-1

3×=-6

×=-6/3=-2

3.2×-8=10

2×=18

×=18/2=9

4.5×-7+2×=4×+5

5×-4×+2×=5+7

3×=12

×=12/3=4

5.5×-2×-4=×+7-5

3×-×=2+4

2×=6

×=6/2=3

6.×-(2×+1)=8-(3×+3)

×-2×-1=8-3×-3

3×=6

×=6/3=2

7.2(×-1)-5=14-×

2×-2-5=14-×

3×=21

×=21/3=7

8.15×-10=6×-(×-2)+(-×+3)

15×-10=6×-×+2-×+3

11×=15

×=15/11

9.×+3(×-1)=6-4(2×+3)

×+3×-3=6-2×-12

6×=-3

×=-1/2

10.6-3(×+1)=-4×+2(1-×)

6-3×-3=-4×+2-2×

3×=-1

×=-1/3
