Giving Brainliest. Using the substitution method and showing all of your steps. Solve the following System of Equations. Make sure to write your answer as an order pair.

`2x+y=20`

`6x-5y=12`

2x+y=20 and -5y=6x+12 are your equations.

You can turn 2x+y=20 into y=-2x+20

Substitute this value of y into the other equation.

-5(-2x+20)=-6x+12

10x-100=-6x+12

16x=112

x=7

Substitute this value of x into the other equation.

2(7)+y=20

y=6

Your answer is x=7 and y=6.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
