Answer: The correct answer is: " x = 0 " .
________
Step-by-step explanation:
Given: " 8 + 8x = 8 " ; Solve for "x" ;
________
Method 1)
________
Subtract "8" from each side of the equation:
________
→ " 8 + 8x − 8 = 8 − 8 " ;
→ On the "left-hand side" of the equation:
Note the following "like terms" :
" +8 − 8 = 0 " ;
→ and we are left with "8x" on the "left-hand side" of the equation.
→ On the "right hand side" of the equation:
The "(8 − 8)" = 0 ;
________
And we are left with:
→ " 8x = 0 " ;
________
Now, divide each side of the equation by "8" ;
to isolate "x" on one side of the equation;
& to solve for "x" :
________
→ 8x / 8 = 0/8 ;
to get:
→ " x = 0 " ;
→ which is the correct answer.
________
Method 2)
________
Given: " 8 + 8x = 8 " ; Solve for "x" ;
________
Subtract "8" from each side of the equation; in the following manner:
________
8 + 8x = 8 ;
- 8 = - 8 ;
_____________
0 + 8x = 0 ;
→ We have: " 0 + 8x = 0 " ;
→ Note: On the "left-hand side" ; we have:
" 0 + 8x " ;
We can simplify this to "8x" ; since the "addition property of zero" states that when "0" is added to any value; the resulting value does not change.
Now, we can bring down the "0" from the "right-hand side" of the equation;
And we can rewrite our equation as:
________
→ " 8x = 0 " ;
Now, divide each side of the equation by "8" ;
to isolate "x" on one side of the equation;
& to solve for "x" :
________
→ 8x / 8 = 0/8 ;
to get:
→ " x = 0 " ;
→ which is the correct answer.
________
Method 3)
________
Given: " 8 + 8x = 8 " ; Solve for "x" ;
________
Divide each side of the equation by "8" ;
________
→ " [tex]\frac{(8 + 8x)}{8} =\frac{8}{8}[/tex] " ;
________
To solve:
________
Note: On the "right-hand side" of the equation:
________
Take note that: " [tex]\frac{8}{8} =[/tex] (8 ÷ 8) = 1 " ;
________
Rewrite the equation as:
________
→ " [tex]\frac{(8 + 8x)}{8} =1[/tex] " ;
________
To solve:
________
Note: " [tex]\frac{x}{y} = z[/tex] " ; ↔ [tex]x = z*y[/tex] ; [tex](y\neq 0)[/tex] ;
________
→ " [tex]\frac{(8 + 8x)}{8} =1[/tex] " ;
→ From the "left-hand side" of the equation;
Let us simplify:
________
→ " [tex]\frac{(8 + 8x)}{8} = \frac{8}{8} + \frac{8x}{8} = 1 + x[/tex] " ;
Now, bring down the "1" from the "right-hand side" of the equation;
and rewrite the equation:
________
→ " 1 + x = 1 " ;
Now, subtract "1" from each side of the equation;
to isolate "x" on one side of the equation;
& to solve for "x" :
________
" 1 + x − 1 = 1 − 1 " ;
→ On the "left-hand side" of the equation:
Note the following "like terms" :
+1 − 1 = 0 " ;
→ and we are left with "x" on the "left-hand side" of the equation.
→ On the "right hand side" of the equation:
The "(1 − 1)" = 0 ;
→ And we are left with:
→ " x = 0 " ;
→ which is the correct answer!
________
The correct answer is: " x = 0 " .
