Question

Solve this equation using the elimination method 4x+2y=6 ; 3x+2y=1

Answer 1

Explanation:

Since they both contain 2y we can just subtract the second from the first to eliminate y

4x+2y-3x-2y=6-1

x=5, since 4x+2y=6 we have

4(5)+2y=6

20+2y=6

2y=-14

y=-7

So the solution point (x,y) is (5,-7)
