Answer 1

B, C, F, H

Explanation:

Just search up how to solve equations

Answer 2

Answer: B. x+2=10

C. x-4=4

F. 3x=24

H.
`(x)/(8)=1`

Explanation:

To check whether 8 is a solution of the given equation or not , we need to substitute the value of 8 in the place of x check whether equation is truw or not.

A.
`x+6=2`

At x= 8, we have

`8+6=2\Rightarrow\ 14=2` , which is not true , it means 8 is not a solution of this equation.

B. x+2=10

At x= 8, we have

`8+2=10\Rightarrow\ 10=10` , which is true , it means 8 is a solution of this equation.

C. x-4=4

At x= 8, we have

`8-4=4\Rightarrow\ 4=4`, which is true , it means 8 is a solution of this equation.

D. x-2=10

At x= 8, we have

`8-2=10\Rightarrow\ 6=10` , which is not true , it means 8 is not a solution of this equation.

E. 2x=4

At x= 8, we have

`2(8)=4\Rightarrow\ 16=4` , which is not true , it means 8 is not a solution of this equation.

F. 3x=24

At x= 8, we have

`3(8)=24\Rightarrow\ 24=24`, which is true , it means 8 is a solution of this equation.

G.
`(x)/(2)=16`

`(8)/(2)=16\Rightarrow\ 4=16`, which is not true , it means 8 is not a solution of this equation.

H.
`(x)/(8)=1`

At x= 8, we have

`(8)/(8)=1\Rightarrow\ 1=1`, which is true , it means 8 is a solution of this equation.

Hence, the required equations :

B. x+2=10

C. x-4=4

F. 3x=24

H.
`(x)/(8)=1`
