Take the first equation and set it to equal x by subtracting 5y from both sides and multiplying by -1.  Looks like this...

-x + 5y = 1
     -5y      -5y
-x = -5y + 1
-1(-x = -5y + 1)
x = 5y - 1   ... substitute this into the second equation you get.....

2(5y - 1) + 4y = -4   answer is #2

Virty [35]

Answer:

<6, <5, <7 all equal 48 degrees.

<1, <2, <3, <4 all equal 132 degrees.

Step-by-step explanation:

Straight angles (like <5 & <2) are supplementary, so they equal 180 when added together

Vertical angles (like <2 & <1) have the same measurments

Corresponding angles (like <8 & <6) have the same measurements

Alternate interior angles (like <8 & <5) have the same measurments

Alternate exterior angles (like <6 & <7) have the same measurements

Same-side interior angles (like <8 & <2) are supplementary, so they add to 180.

There's more, and there's other ways to do this, this is just an example. Good luck! <3
