Question

–5x + 3y = 6
x – y = 4

Answer 1

have you tried to solve this by elimination

Answer 2

I would multily the bottom equation by 3
and add the equations together after that
this will result in the elimination of y
and you will be able to solve for x first

Answer 3

so is (–9, –13)

Answer 4

following the directions above to solve by elimination,
(-5+3 ) x =6 + 12
x = 18/-2 = -9

y = x + 4 = -9 + 4 = -5

Answer 5

y=x-4=-9-4=-13

Answer 6

check in –5x + 3y = 6
-5(-9) + 3 (-5) = 45-15 = 30 error
@myininaya thanks I see my error

Answer 7

We all make them.
I make them more than most.

Answer 8

LHS: -5(-9) + 3(-13) = 45 -39 =6 = RHS
