Question 212098This question is from textbook Geometry
: How would you solve:
-3x+y=7
3x+2y=2
using elimination This question is from textbook Geometry
You can put this solution on YOUR website! Add the two equations together:
-3x+y=7
3x+2y=2
--------
0x+3y= 9
3y = 9
y = 3
.
Substitute the above into equation 1 and solve for x:
-3x+y=7
-3x+3=7
-3x=4
x = -4/3
.
Solution:
x = -4/3
y = 3
Or, (x,y) = (-4/3, 3)
