Is the equation true, false, or open? 5x+2=6x+11

Hi Brainiac

5x+2=6x+11

Before we know if it is true or false the first thing we need to do is to solve the equation 

5x+2=6x+11

Combine like terms

5x-6x=11-2

-x=9

Divide both sides by -1

-x/-1 = 9/-1

x=-9

Now we gonna replace -9 everywhere we find x

5x+2=6x+11

5(-9)+2= 6(-9)+11

-45+2 = -54+11

-43 = -43

Yes The equation is true because as you can see the both sides of the equation equal to each other.

I hope that's help and good luck :)

Please if you have question(s) about something you don't really understand you can just ask and I will try my best.

Have a great summer :)

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
