Ahmad is thinking of a number.
If he multiples the number by 2 and adds 14, the result is the
same as if he subtracts 8 from 4 times the number.
Let the number be x. write an equation in terms of x
Solve the equation.
Find the result.

Quadratic equation is
2x+14 =4x-8
Bring all the x co-efficients to one side and constants to one side , then we get
- 4x-2x=14+8
- 2x=22
- x= 22/2=11
- so for the value of x = 11 the given equation is suitable
- If the answer is correct and if you like it, then
- Mark it as a brainleist answer and thank me

Answer:
Let x be the unknown
1st line=2x+14
2nd line =4x-8
Therefore,since the results are the same
The equation,
2x+14=4x-8
2x-4x=-8-14
-2x=-22
Divide both sides by the coefficient of x
-2x/-2 =-22/-2
X=11
