Question

3)Resolva usando a propriedade distributiva: a)2. (x + 2 ) =10 b) 3 . (x +3 ) =18 c) 4. ( y + 4) =24 d)5 . ( x – 2) =20 PRECISO PARA HJ PLEASE!!!

Answer 1

a) 2(x + 2) = 10

2x + 4 = 10

2x = 10 - 4

2x = 6

x = 6 / 2

x = 3

b) 3(x + 3) = 18

3x + 9 = 18

3x = 18 - 9

3x = 9

x = 9 / 3

x = 3

c) 4(y + 4) = 24

4y + 16 = 24

4y = 24 - 16

4y = 8

y = 8 / 4

y = 2

d) 5(x - 2) = 20

5x - 10 = 20

5x = 20 + 10

5x = 30

x = 30 / 5

x = 6
