Question

What is the elimination method for this problem
4x-3y=22
2x-y=10

Answer 1

4x - 3y = 22 ⇒ 4x - 3y = 22 ⇒ 4x - 3y = 22
2x - y = 10 ⇒2(2x - y) = 10 ⇒ 4x - 2y = 10
5y = 32
5y = 32
5 5
y = 6.4
4x - 3(6.4) = 22
4x - 19.2 = 22
+ 19.2 + 19.2
4x = 41.2
4x = 19.2
4 4
x = 4.8
(x, y) = (4.8, 6.4)

Answer 2

4x-3y=22
2x-y=10
4y-2y-20
-y=2
y=-2
i think that is the answer...
