UkoKoshka [18]
-6x - 4y = 12|\div 2\\&#10;12y = -18x - 36|\div 6\\\\&#10;-3x-2y=6\\&#10;2y=-3x-6\\\\&#10;-3x-2y=6\\&#10;-3x-2y=6

Both equations are equivalent, so there are infinitely many solutions.

The product of nine and a number is added to six the result is 24 what is the number
Andru [333]
Hello!

We can make an equation based on what we know

The product of 9 and a number is

9 * x

Added to six

9 * x + 6

Gives the result of 24

9 * x + 6 = 24

Now you solve it algebraically

Subtract 6 from both sides

9 * x = 18

Divide both sides by 9

x = 2

The answer is 2

Hope this helps!

How Do I do proofs for proving triangles?
MA_775_DIABLO [31]
You must have been taught postulates and theorems that allow you to prove triangles congruent, such as SSS, SAS, ASA, etc. Look at the given information of a proof, and see how from the given information, using definitions, postulates, and theorems you have already learned, you can show pairs of corresponding sides and angles to be congruent that will fit into the above methods. Then use one of the methods to prove the triangles congruent.
