Solve by substitution: <br> -5x + y = -2<br> -3x + 6y = -12<br><br> please explain
fomenos

First we pick the equation. Let's say we pick first one. From it we express y.

-5x+y=-2\Longrightarrow y=-2+5x

Then we use this y and plug it in instead of y in the second equation.

-3x+6(-2+5x)=-12

Now just solve for x.

-3x-12+30x=-12 \\-3x=-30x \\\underline{x=10}

We plug this x in the first equation.

-5\cdot10+y=-2

And solve for y.

-50+y=-2 \\\underline{y=48}

So the solution to the equation is geometrically a point P which lies on the intersection of the two lines.

\boxed{P(10,48)}

Hope this helps.

Henry found some pants on sale for 60% off. If the pants were originally $100, how much are they now?
vredina [299]
If something is 60% off, that means it is now going to be 40% of its original price because

100 - 60 = 40

To find final price multiply the percentage as a decimal by the price.

40% is 40/100 which as a decimal is 0.4

0.4 x 100 = $40

The pants will be 40 dollars.
