Answer: X= 1 Y= -1 Explanation: Step 1: Get the y in 5x-y=6 alone on one side of the equation by adding it over to the other side (5x=6+y) then subtract the 6 to the other side (5x-6=y) Step 2: plug this entire new equation in for y on your other equation it is now 2x+7(5x-6)=-5 Step Three: distribute the 7 to all parts in parentheses (2x+35x-42=-5) Step 4: combine like terms 37x-42=-5 Step 5: Add the 42 to the other side 37x=42-5 —> 37x=37 Step 6: Divide by 37 on both sides to find x 37/37= 1 (1=x) Step 7: Plug your x value in as x for either equation Ex: 2(1)+7y=-5 2+7y=-5 7y=-5-2 7y=-7 7/-7=-1 Y=-1 Or 5(1)-y=6 5-y=6 5=y+6 5-6=y -1=y
