Answer:
8+5 = x - 7
Explanation:
a number is X
sum means addition
difference means subtraction
To solve: You need to isolate x on one side of the equation (one side of the = sign). To do this, add 7 to both sides so you can move it from one side to the other:
8 + 5 = x - 7
+7 +7
As you can see, adding 7 will cancel out the - 7 on the right side, and move it to the left. Now the equation you are left with is
8 + 5 + 7 = x
Finally add the numbers together and you will get your value for x.
8 + 5 + 7 = 20
20 = x
We have that for the Question "The sum of 8 and 5 is equal to the difference of a number and 7" it can be said that The value of x is
[tex]x=\frac{13}{7}[/tex]
From the question we are told
The sum of 8 and 5 is equal to the difference of a number and 7
Generally the equation for the Statement is mathematically given as
[tex]8+5=x+7\\\\Therefore\\\\x=\frac{8+5}{7}\\\\[/tex]
[tex]x=\frac{13}{7}[/tex]
Therefore
The value of x is
[tex]x=\frac{13}{7}[/tex]
