Question

15 - x - = 4
$15 - x = 4$
​

Answer 1

Answer:

$\Huge \boxed{X=11}$

Step-by-step explanation:

To solve this problem, first you have to isolate it on one side of the equation. Remember to solve this problem, addition property of equality is adding from both sides of an equation the same number doesn't change the equation.

First, subtract 15 from both sides,

$\displaystyle 15-x-15=4-15$

Solve.

$\displaystyle 4-15=-11$

$\displaystyle -x=-11$

Next, divide by -1 from both sides.

$\displaystyle \frac{-x}{-1}=\frac{-11}{-1}$

Solve.

$\displaystyle -11\div-1=\boxed{11}$

It change negative to positive sign.

In conclusion, the correct answer is x=11.

Hope this helps!

Have a wonderful blessing day! :)

Good luck! :)

______________ [ GIVEN ]

We have to find the value of x.

______________________________

We have to simply solve this equation.. 15 - x = 4. To find value of x.

=> 15 - x = 4

=> - x = 4 - 15

=> - x = - 11

=> x = 11
