Question

obtenha a solução de cada equação a)2x=16 b)y+5=9 c)3z -1 =14 d)7=19-2x​

Answer 1

a)2x=16

x= 16/2

x= 8

b)y+5=9

y= 9 - 5

y= 4

c)3z -1 =14

3z = 14 + 1

3z = 15

z= 15/3

z= 5

d)7=19-2x

- 2x + 19= 7

- 2x = 7 - 19

- 2x= - 12

x= - 12/-2

x= 6

Answer 2

a) 2x=6

x=16/2

x=8

b) y+5=9

5y=9

y=9/5

y=1.8

c) 3z-1=14

3z=14+1

3z=15

z=15/3

z=5

d) 7=19-2x

2x=19+7

2x=26

x=26/2

x=13
