You can put this solution on YOUR website! 1) x = 8y - 3
2) x = 2y - 9
:
use equation 1) and substitute for x in equation 2)
:
8y - 3 = 2y - 9
:
subtract 2y from both sides of =
:
6y - 3 = -9
:
add 3 to boh sides of =
:
6y = -6
:
divide both sides of = by 6
:
y = -1
:
we can use either equation 1 or 2 and substitute for y
:
use equation 1)
:
x = 8(-1) -3
:
x = -11
:
*****************************************
x = -11 and y = -1
:
check our answer
:
equation 1
:
-11 = 8(-1) -3
:
-11 = -11
:
equation 2
:
-11 = 2(-1) -9
:
-11 = -11
:
our answers check for equations 1 and 2
