Say x is the number
7x +3 = 39 -2x
Add 2x to each side
9x +3 =39
Subtract 3 from each side
9x =36
Divide by 9 on each side
x=4
Hope this helped
Original price of the swimsuit = x
If something was discounted 65%, that means you are paying 35% for it.
(100% - 65% = 35% or 0.35)
x(0.35) = 20.30
divide both sides by 0.35
x = 58
The swimsuit was originally 58 dollars.

which problems? i can teach you how to do them if you want me too.
Answer:
x = 83.2
Step-by-step explanation:
Let the unknown number be x
-90 * (x - 83) = x + (-99)
-90x + 7470 = x - 99
Subtract x from both sides
-90x - x + 7470 = x - x - 99
-91x + 7470 = -99
Subtract 7470 from both sides
-91x + 7470 - 7470 = -99 -7470
-91x = -7569
Divide both sides by -91
x = 83.2
