Question

A)X+7= -3

B)5X=30

C)5X=15

D)-3X=6

E)3Y=18

Answer 1

A)X+7= -3

x= - 3 - 7

x= - 10

B)5X=30

x= 30/5

x= 6

C)5X=15

x= 15/5

x= 3

D)-3X=6 (-1)

3x= - 6

x= - 6/3

x= - 2

E)3Y=18

y= 18/3

y= 6

Answer 2

resolução!

A )

x + 7 = - 3

X = - 3 - 7

X = - 10

B )

5x = 30

X = 30/5

X = 6

C )

5x = 15

X = 15/5

X = 3

D )

- 3x = 6

X = - 6/3

X = - 2

E )

3y = 18

Y = 18/3

Y = 6
