Idon’t get this lesson so might need

Explanation:

The variable b is the placeholder for the original price, aka price before discount.

We discount by 25% meaning we don't pay that 25% but instead pay the remaining 75%

Therefore the expression 0.75*b represents the final price after the discount. We're told this price is $1.50 so that is how I'm getting the answer to be 1.50 = 0.75b

Extra info:

To solve this equation for b, you would divide both sides by 0.75 to undo the multiplication that is happening.

1.50 = 0.75b

1.50/0.75 = 0.75b/0.75 dividing both sides by 0.75

2.00 = b

b = 2.00

So the original price before discount was $2.00; note how 25% of this is 0.25*2.00 = 0.50 which is the amount we save and the amount we have left is 2.00 - 0.50 = 1.50 which is the proper price after discount we want.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
