Which of the following is a solution to the system of linear equations below?
2 answers:
Its C.
If we substitute x=2 and y=-5 into C we get
2(2) = 4 and 15-11 = 4
2(-5) = -10 and 6(2) - 22 = -10
Hello!
First, let's solve the second equation for y.
2y=6x-22
Divide both sides by 2.
y=3x-11
Now we can plug this into the first equation to solve for x.
2x= -3(3x-11)-11
2x=-9x+33-11
2x=-9x+22
Subtract 9x from both sides.
-11x=22
Divide both sides by -11
x=-2
Now we plug this into the simplified version of the second equation.
y= 3(2)-11
y=6-11
y=-5
Therefore, our answer is D. (-2,-5)
I hope this helps!
