Answer:
Explanation:
2x + y = 5.....multiply by -3
3x - 2y = 4...multiply by 2
--------------------------
-6x - 3y = -15 (result of multiplying by -3)
6x - 4y = 8 (result of multiplying by 2)
-------------------------add
-7y = - 7 <===== here is one mistake.....its -7, not 7
y = -7/-7
y = 1
now sub 1 in for y in either of ur original equations to find x
not sure why u r multiplying again on ur paper when all u have to do is sub
2x + y = 5
2x + 1 = 5
2x = 5 - 1
2x = 4
x = 4/2
x = 2
solution is : (2,1)
the bad part about elimination is if there is a mistake made in the first part, it carries through to the end. So it is always best to check ur answers.
