Answer: B. x+2=10
C. x-4=4
F. 3x=24
H. [tex]\dfrac{x}{8}=1[/tex]
Step-by-step 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. [tex]x+6=2[/tex]
At x= 8, we have
[tex]8+6=2\Rightarrow\ 14=2[/tex] , which is not true , it means 8 is not a solution of this equation.
B. x+2=10
At x= 8, we have
[tex]8+2=10\Rightarrow\ 10=10[/tex] , which is true , it means 8 is a solution of this equation.
C. x-4=4
At x= 8, we have
[tex]8-4=4\Rightarrow\ 4=4[/tex], which is true , it means 8 is a solution of this equation.
D. x-2=10
At x= 8, we have
[tex]8-2=10\Rightarrow\ 6=10[/tex] , which is not true , it means 8 is not a solution of this equation.
E. 2x=4
At x= 8, we have
[tex]2(8)=4\Rightarrow\ 16=4[/tex] , which is not true , it means 8 is not a solution of this equation.
F. 3x=24
At x= 8, we have
[tex]3(8)=24\Rightarrow\ 24=24[/tex], which is true , it means 8 is a solution of this equation.
G. [tex]\dfrac{x}{2}=16[/tex]
[tex]\dfrac{8}{2}=16\Rightarrow\ 4=16[/tex], which is not true , it means 8 is not a solution of this equation.
H. [tex]\dfrac{x}{8}=1[/tex]
At x= 8, we have
[tex]\dfrac{8}{8}=1\Rightarrow\ 1=1[/tex], 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. [tex]\dfrac{x}{8}=1[/tex]
