Using elimination process what is the answer for

14x+2y=18

-7x-4=9

use steps

Step 1; multiple equation 2 by - 2: 14x+8y=-18

step2: subtract this new equation from equation 1 to eliminate x:

2y-8y=18 - (-18)

-6y=36

y=-6

step 3: substitute y=6 in equation 2: - 7x-4 * (-6) = 9, - 7x=-15, x=15/7
