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.

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

You'd have to include a picture of the figure. A rotation moves it around a fixed point, a translation moves it left, right, up, or down without changing the direction it faces or its size. A reflection is a mirror image and a dilation changes its size.
