Answer:
you plug in (y) with the top equation
Step-by-step explanation:
step 1: 2x+1/2x-1=-6
step 2: 2.5x-1=-6
step 3: 2.5x-1=-6
+1. +1
step 4: 2.5x= -5. Divide both sides by 2.5
-5/2.5 = -2
step 5: plug in your (x) to find (y)
y= 1/2(-2)-1
step 6: 1/2(-2) = -1
y=( -1)-1
y=-2
step 7: (x,y)= (-2,-2)
step 8: graph your coordinate
I hope that this helped you!

Lets say u want an item that originally cost $ 50.....and u get a 25% discount....then u are actually subtracting 25% of the original price.
25% of 50 .....turn the percent to a decimal..." of " means multiply
0.25 * 50 = 12.50.....so u would be subtracting 12.50 from $ 50 for the discounted price which is (50 - 12.5) = 37.5
here is another example...
u want an item that costs $ 90....and it is 25% off.....so u would be subtracting (25% of 90).......u would be subtracting (0.25 * 90) = 22.50 from the original price to arrive at the discounted price.
90 - 22.50 = 67.50...the discounted price
But let me show u something....taking 25% off is the same as paying 75%..
so lets say u want an item that costs $ 60....and u get a 25% discount...this means u r actually paying 75%.....ur paying 75% of 60.
0.75 * 60 = $ 45...this is what u r paying....no need for subtracting
