What is does x equal when 2x+4=16?

x = 6

Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is 2x.

Since 4 is being added to 2x, we subtract 4 from both sides of the equation to isolate the 2x.

On the left, the +4 and -4 cancel out and on the right, 16 - 4 is 12.

So we have 2x = 12.

Now we can finish things off by just dividing

both sides of the equation by 2.

On the left the 2's cancel and on the right, 12 divided by 2 is 6 so x = 6

x=6

Step-by-step explanation:

2x+4=16

2x=16-4

2x=12(divide both sides by 2 to get x)

2x/2=12/2

x=6

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
