Question 90517
original
5x-2y=10
y=3x-5

5x-2(3x-5)=10
Remember order of operations and combine like terms.
5x-6x+10=10
      -10 -10
5x-6x=0
-x=0
/-1 /-1
x=0
To find y we then subtitute our found value for x it into the original problem to complete our pair.
5(0)-2y=10
0-2y=10
-2y=10
/-2  /-2
y=-5
our ordered pair is (0,-5)
To check to see if our answers are correct, then we plug in our answers for our ordered pair into the original equation.
5(0)-2(-5)=10
0+10=10
10=10
true
