Question

2x+5=12
Show me the working out

Answer 1

`\sf{x=(7)/(2)=3.5 }`

Explanation:

It is necessary to isolate the term of x from both sides in order to solve this problem.

First, subtract by 5 from both sides.

2x+5=12

`\sf{2x+5-5=12-5}`

Solve.

`\sf{12-5=7}`

2x=7

Divide by 2 from both sides.

2x/2=7/2

Solve.

Dividing is another option.

7/2=3.5

So, the final answer is 7/2=3.5.

I hope this helps you! Please let me know if my answer is wrong.
