Question

Solve the system using elimination.

SHOW ALL WORK on a separate sheet of paper.
52 - 2y = -48
2x + 3y = -23

Answer 1

y=50 and x=-173/2

Explanation:

52-2y=-48

∴-2y=-100

y=50

and 2x+3y=-23

y=50→(1)

2x+3y=-23→(2)

Putting y=50 in equation (2), we get

⇒2x+3y=-23

⇒2x+3(50)=-23

⇒2x+150=-23

⇒2x=-23-150

⇒2x=-173

⇒x=-173/2

∴y=50 and x=-173/2
