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.

I'm having a hard time solving this<br> May I please have an explanation
Marina CMI [18]

Answer:

e = 9

Step-by-step explanation:

ok e is just x, so we have to get it alone

4e - 10 = 2e + 8

We move the 2 since its smaller than the 4, and we move it two the other side. 4-2=2 so the new e is 2, now that 8 is alone (since we moved the 2), we cant be having the e with the -10... like this..

2e - 10 = 8, so we now add 10 so it can go with the 8, the new equation is this..

2e = 18

18/2 = 9

simple explanation

4e - 10 = 2e + 8

2e = 18

e = 9

(does that make sense)
