Por favor me ajudem ,é urgente

Answer 1

A) 2× +4=×-6 
2x -x = -6 -4
x= -10

B) 3×=15
x= 15/3
x= 5

C) 4×-2=18
4x = 18 +2
4x = 20
x= 20/4
x= 5

D) 2×+5=25
2x= 25-5
2x=20
x=20/2
x=10

E)6×+2=-2×+14
6x -2x = 14-2
4x =12
x=12/4
x=3

F) 3(×+1)=12
3x +3 = 12
3x = 12-3
3x = 9
x=9/3
x=3

G) 5(×+2)=2(×-2)
5x +10 =  2x -4
5x-2x=-4-10
3x = -14
x=-14/3

H)9×-4=54
9x = 54+4
9x=58
x=58/9
