Step 1: Where you see a y in the equation 6x + 4y =14 replace it with 5. This will help you find x

6x + 4(5) = 14

6x + 20 = 14

Step 2: Combine like terms by subtracting 20 to both sides

6x + (20-20) = 14-20

6x = -6

Step 3: Isolate x by dividng 6 to both sides


(6x)/(6) = (-6)/(6)

x = -1

Point of intersection of these two linse is ( -1 , 5 )

Hope this helped!
