Question

Solve 2x +5=12 answer?!

Answer 1

Answer:

x = 3.5

Step-by-step explanation:

To solve this you need to solve for x.

This is a two step equation so you need to first subtract 5 from itself and whatever you do to one side of the equation you have to do to the other side as well.

So 5 - 5 = 0

12 - 5 = 7

Then the equation becomes 2x = 12

Now it is a one step equation, so find the inverse operation of multiplication, which is division .

So 2 divided by 2 is 1 which also equals x by itself

7 divided by 2 equals 3.5

So x = 3.5

Answer 2

Answer:

$\huge\boxed{x=\frac{7}{2}, x=3.5}$

Step-by-step explanation:

Subtract by 5 from both sides of equation.

$\displaystyle 2x+5-5=12-5$

Simplify.

$\displaystyle 12-5=7$

$\displaystyle2x=7$

Divide by 2 from both sides of equation.

$\displaystyle \frac{2x}{2}=\frac{7}{2}$

Simplify, to find the answer.

$\displaystye x=\frac{7}{2}, x=3.5$

x=7/2 and x=3.5 is the correct answer.
