Solve by elementation
-4x-3y=-14
12x+5y=2
show work or explain cause i don't understan

I don't understand can you show have to do this pleas

Elimination occurs when you add or subtract each equation in order to isolate one variable.

In this case, the first equation can be multiplied by 3. This will get you a -12x in one equation and a 12x in the other.

-12x - 9y = -42
12x + 5y = 2

Now add the second equation to the first to cancel the -12x and 12x.

-4y = -40

Now divide both sides by -4.

y = 10

Plug in the y value for one of the original equations and solve.

12x + 5(10) = 2
12x + 50 = 2
12x = -48
x = -4

Your solution set is (-4, 10)

The scale factor of what ?

Could you make it more clear?
