SOLUTION: equations in three linear variables 2x-y+z=10 4x=2y-3z=10 x-3y+2z=8 wouldn't you multiply the first equation by 3?

Question 44703: equations in three linear variables
2x-y+z=10
4x=2y-3z=10
x-3y+2z=8
wouldn't you multiply the first equation by 3?
Answer by corrie21(4) (Show Source): You can put this solution on YOUR website!
Yes, if you multiply the first equation by 3, it will cause the z's to cancel out. Next you would multiply the first one by a negative 2 to cross the z's out again. Then you would use the 2 new equations you just got and solve for either x or y.
