The solution of given equation 10 ax + 11 ax = 12ax +45 is x = 5/a.
The correct answer is an option (B)
What is an equation?
"It is a statement which consists of equal symbol between two mathematical expressions."
For given example,
We have been given an equation 10 ax + 11 ax = 12ax + 45
We need to solve given equation for x.
Assuming a ≠ 0,
⇒ 10 ax + 11 ax = 12ax +45
⇒ (10 + 11) ax = 12 ax + 45 ...............(Separate out common terms)
⇒ 21 ax = 12 ax + 45
⇒ 21 ax - 12 ax = 12ax + 45 -12 ax ...........(Subtract 12 ax from each side)
⇒ (21 - 12) ax = 45 ...............(Separate out common terms)
⇒ 9 ax = 45
⇒ 9ax/9a = 45/9a ..............(Divide both the sides by 9a)
⇒ x = 5/a
Therefore, the solution of given equation 10 ax + 11 ax = 12ax +45 is x = 5/a.
The correct answer is an option (B)
