Question

Solve using substitution:
6y − x − 9 = 0
-4x = -5y − 2

A. No solution
B. Infinitely many solutions
C. (-4, -1/6)
D. (3, 2)

Answer 1

first, solve for "Y" in your second eqaution:
-4x = -5y -2
-4(0) + 5y = -2
5y = -2
y = -2/5

now plug "Y" into your first equation and solve for "X"
6(-2/5) - x = 9
-12/5 - x = 9
-x = 33/5
x = -33/5

either i royally screwed up or there is no solution to this answer o.O (its probably the first one) you may want to clarify with someone

Answer 2

@jollysailorbold ^^^

Answer 3

hi!

Answer 4

hello (: can you help me with this problem ?

Answer 5

yeah give me a bit:)

Answer 6

he royally screwed up because i got this: x=3
y=2

Answer 7

unless i royally screwed up too.

Answer 8

seems a lot better than mine at this point lol, i would go with jollies

Answer 9

(-x+6y=9)4
-4x+5y=-2
this gives...........
-4x+24y=36
-4x+5y=-2
on solving these two equations we get:-
19y=38
=>y=38/19
=>y=2
on putting y=2 in equation no 1, we get......
-x+6y=9
-x+6.2=9
=>x=3

Answer 10

is this fine?????
