Answer:
75
Step-by-step explanation:
5x-9+9x-6=111
14x-15=111
14x= 126
x=9
-6+9(9)= 75
Answer:
Ah, I have this problem. I'm not sure if this would help you but I typically put on some of my favorite music which tends to get me pretty hyped up. By then I'm not so reluctant to do my school work. You can also think of something that your excited to do later which might encourage you to get your school work done so you can do that activity. Hope this helps, have a good day!
Step-by-step explanation:
-x-y=-9
-3x-2y=-28
eliminate the x first
multiply the first system of equations by 3
(3)(-x)=-3x
(3)(-y)=-3y
(3)(-9)=-27
-3x-3y=-27
-3x-2y=-28
eliminate the systems of equations by subtracting
-3x--3x-3y--2y=-27--28
-3x+3x-3y+2y=-27+28
-y=1
multiply -1 for -y=-1 to get positive y
(-y)(-1)=(1)(-1)
y=-1
substitution method by using y=-1 into one of the system of equations
-x-y=-9
-x--1=-9
-x+1=-9
move +1 to the other side
sign changes from +1 to -1
-x+1-1=-9-1
-x=-10
multiply by -1 for -x=-10 to get positive x
(-x)(-1)=(-10)(-1)
x=10
answer:
x=10, y=-1
