What is the elimination method for this problem
4x-3y=22
2x-y=10
2 answers:
4x-3y=22
2x-y=10
4y-2y-20
-y=2
y=-2
i think that is the answer...
4x - 3y = 22 ⇒ 4x - 3y = 22 ⇒ 4x - 3y = 22
2x - y = 10 ⇒2(2x - y) = 10 ⇒ <u>4x - 2y = 10</u>
5y = 32
<u>5y</u> = <u>32
</u> 5 5<u>
</u> y = 6.4
4x - 3(6.4) = 22
4x - 19.2 = 22
<u> + 19.2 + 19.2
</u> 4x = 41.2
<u>4x</u> = <u>19.2</u>
4 4
x = 4.8
(x, y) = (4.8, 6.4)
