What is the value of x in the equation −x = 2 − 3x + 6?
Wittaler [7]
-x = 2 - 3x + 6

Add 3x to both sides.

-x + 3x = 2 + 6

Simplify.

2x = 8

Divide both sides by 2.

x = 4

Help :( I suck at math
iris [78.8K]

Answer:

D

Step-by-step explanation:

For some side lengths to create a triangle, any two of the side lengths must have an added length together of less than the third leg. Otherwise, the vertices would simply not be able to be connected by the lines. In a), 3+5=8, but since it is not more, the triangle will not be able to be formed (it would basically just be a line.) In B, 7+8< 16. In C, there is the same situation as with the first example (4+15=19). Finally, in the last one, 5+7>12, and all of the side lengths work out. Therefore, the correct answer is D. Hope this helps!

In the solution of the equation 5 + 3x = -2x + 9, 2 x is added to the equation first. which of the following should be done next
wariber [46]

Hi!

<h3>Let's do the first step (add 2x). </h3>

5 + 3x + 2x = -2x + 2x + 9

<em>5 + 5x = 9</em>

<h3>Our goal is to isolate x on one side, so the next step would be to subtract 5 (or add -5).</h3>

5 + -5 + 5x = 9 + -5

<u><em>5x = 4</em></u>

<h2>The answer is B. add -5</h2><h3><em>And if you want to finish solving, you would divide by 5 on both sides.</em></h3>

5x/5 = 4/5

x = 0.8

Hope this helps! :)
