If you passed 9th grade math you could answer this! Please help! Solving system by substitution

Posted on 2014-03-26 09:12:00 in Math by

I missed a week of school because I was in the hospital and I missed the whole chapter 5. My teacher said if I don't get all my assignments in by this wednesday he is going to fail me!! Literally no questions asked. This is ridiculous and probably the worst thing ever. I have a slight understanding of this but it would be so amazing if someone could do these problems for me. I literally have like 7 other assignments.



5.2 Solve each system by substitution:



1. y=5x+3

y=4x+4



2. y=-4+18

y= -3x+13



3. y=5x+20

y=-2x-8



4. y=-5x-21

y=-2x-6



5. y=3x-8

y=-4x+6



6. y=-4x+18

y=3x-3



7. -3x-7y=4

y=-3x+20



8. -9+3y=-7

y=3x-7



9. y= 4x+6

-8x-4y=24



10. -2x+6y=10

-4x+y=9



11. -7x+6y=-12

x-7y=14



12. 8x+2y=-10

-2x+y= 7
