Question

What is 12+24=2(6+ )

Answer 1

12+24=2(6+x )

36=2(6+ )

36\2=(6+x)

18=(6+x)

18-6=x

12=x

the answer is 12

Answer 2

`\huge \boxed{x=12}`

Explanation:

Let the unknown number be x.

12+24=2(6+x)

Switch sides.

2(6+x)=12+24

Expand brackets.

12+2x=12+24

Subtract 12 from both sides of the equation.

12+2x-12=12+24-12

2x=24

Divide both sides of the equation by 2.

(2x)/2=24/2

x=12
