Question

Propriedade Distributiva. .

Me ajudem por favor

A)3(x+4)=96
B)2(x-3)=12
C)4(x-1)=24
D)6(x+2)=30
E)7(x-1)=49
F)8(x-3)=64
G)5 (x+3)=45
H)5(x+4)=100

Answer 1

A) 3x +12 = 96
3x = 96-12
x = 84
X = 84/3 = 28

B) 2x -6=12
2x = 12+ 6
2X= 18
X= 18/2 x= 9

C) 4x -4 = 24
4x= 24+ 4
X= 28/4
X= 7

D) 6x+12=30
6x=30-12
X=18/6 x= 3

E) 7x-7=49
7x= 49+7
7x= 56
X=56/7 x= 8

F) 8x-24=64
8x= 64+24
8x= 88
X= 88/8 x= 11

G)5x +15=45
5x= 45-15
5x = 30
X=30/5 x=6

H) 5x+20=100
5x= 100-20
5x= 80
X= 80/5 x= 16

Espero ter ajudado!...
