A coupon subtracts $17.95 from the price p of a pair of headphones. You pay $71.80 for the headphones after using the coupon. Wr

Nady [450]

Answer:

x - 17.95 = 71.80, $89.75

Step-by-step explanation:

Let the original price of the headphones be x

Amount of coupon = $17.95

You pay the final amount for the headphones after using the coupon = $71.80

So to find the original price of the headphones, the equation will be

x - 17.95 = 71.80

x = 17.95 + 71.80

x = $89.75

The original price of the headphones would be $89.75

4x+2(3x-9)=42 what is x equal

katrin2010 [14]

<span>4x+2(3x-9)=42
first we want to distribute the 2 using the distributive property
4x+6x-18=42
Then we simplify
</span><span>10x-18=42
we add 18 to both sides
10x=60
divide both side by 10
x=6</span>
