Answer :

Let's solve the equation step-by-step:

The given equation is:

[tex]30 \times 40 - 60 \times 20 + x = 11[/tex]

First, perform the multiplications:

  1. Calculate [tex]30 \times 40 = 1200[/tex].
  2. Calculate [tex]60 \times 20 = 1200[/tex].

Now, substitute these results back into the equation:

[tex]1200 - 1200 + x = 11[/tex]

Simplify the equation:

[tex]0 + x = 11[/tex]

This simplifies further to just:

[tex]x = 11[/tex]

So, the value of [tex]x[/tex] that satisfies the equation is [tex]11[/tex].

This equation involves basic arithmetic and algebra concepts. We simply used the order of operations (multiplication before addition/subtraction) to simplify and solve the equation for [tex]x[/tex]. The solution indicates that the unknown variable [tex]x[/tex] is equal to [tex]11[/tex].
