3( 1/2 - y) = 3/5 + 15y
Applying distributive property:
3*1/2 - 3y = 3/5 + 15y
3/2 - 3y = 3/5 + 15y
3/5 is adding on the right, then it will subtract on the left
3y is adding on the left, then it will subtract on the right
3/2 - 3/5 = 15y + 3y
15/10 - 6/10 = 18y
9/10 = 18y
18 is multiplying on the right, then it will divide on the left
9/10*1/18 = y
1/10*1/2 = y
1/20 = y
An item that costs $30, when discounted 15 percent, will cost $25.5. The easiest way of calculating discount is, in this case, to multiply the normal price $30 by 15 then divide it by one hundred. So, the discount is equal to $4.5. To calculate the sales price, simply deduct the discount of $4.5 from the original price $30 then get $25.5 as the sales price.

5x + 4 = 7x
Subtract 4 from both sides.
5x = 7x - 4
Subtract 7x from both sides.
5x - 7x = -4
Simplify.
-2x = -4
Divide both sides by -2.
x = 4/2
x = 2
