Question

determine o valor de x

6(x-1 )=18

8(+3)=48

4(x-2)=20

10(x-5)=40​

Answer 1

Resposta:

6(x-1 )=18

6x -6 = 18

6x = 18 + 6

6x = 24

x = 24/6

x = 4

8(x+3)=48

8x + 24 = 48

8x = 48 - 24

8x = 24

x = 24/8

x = 3

4(x-2)=20

4x - 8 = 20

4x = 20 + 8

4x = 28

x = 28/4

x = 7

10(x-5)=40

10x - 50 = 40

10x = 40 + 50

10x = 90

x = 90/10

x = 9
