How do you solve for x and y in the following equations using substitution? ?

y+2x=10 and 2y-x=10

you s xd

Y=-2x+10 and y=1/2x+5

If y+2x=10, then y=10-2x
then you use this equation in the: 2y-x=10
that means… 2(10-2x)-x=10
20-4x-x=10
-5x=10-20
so x= 2
after that you put x value in the second equation:
y+4=10
y= 10-4=6
Hope that is OK for you.

Yes you do, so £1973.09 - £1473.50 = £499.59 so tim overpaid £499.59 .hope this ; )
