Answer: 5
Explanation:
8x � 11 = 2x + 1
Subtract 2x from both sides of the expression....
8x � 11 - 2x = 2x + 1 - 2x
==> 8x - 2x - 11 = 2x - 2x + 1
==> 6x - 11 = 1
Add 11 on both sides....
==> 6x - 11 + 11 = 1 + 11
==> 6x = 12
Divide both sides by 6....
==> 6x/6=12/6
==> x = 2
That x = 2 is the solution of the given equation...
To check your solution you have to substitute the value of x in the given expression
8 * 2 � 11 = 2 * 2 + 1
==> 16 - 11 = 4 + 1
==> 5 = 5
That is you have same value on either sides of the given expression
Means your solution is correct/ Hope this helped!
