Step-by-step explanation:
Square both sides of the equation.
Answer:
x=7
Step-by-step explanation:
To set up for this answer, we need to set it up as an equation: 2x+12=5x-9.
get the xs on one side and the whole numbers on the other.
that leaves you with 21=3x.
divide by 3 on both sides to get the answer of x=7
Equal because 30 is the median and when you find the mean, it is also 30. Please give brainliest!

Answer:
<u><em>Vertical angles are</em></u><u><em> congruent</em></u><u><em>, so the</em></u>
<u><em>equation </em></u><u><em>3x-6 = 114</em></u><u><em> can be used to find x.</em></u>
<u><em>The value of x is </em></u><u><em>40</em></u><u><em>.</em></u>
<u><em /></u>
<u><em>Convince Me!</em></u>
<u><em>Why can you use an equation when solving for x in</em></u>
<u><em>the diagram?</em></u>
<u><em>You can use the eqution because they are equal to each other. When they are equal to each other, you can find x by using the equation to simplify and get x alone.</em></u>
