How do you solve for x in a math question like this 5+4x=54-3x?
Bas_tet [7]

To solve for x, first you need to isolate all x terms on the same side so:

you start with 5 + 4x = 54 - 3x

subtract 5 from both sides to get 5 onto the left side

now you should have 4x = 49 - 3x

now add 3x to both sides to get 3x onto the right side

now you should have 7x = 49

now that you have your x on one side you can solve this like a regular one step equation and divide both sides by 7

this leads you to your answer of x = 7

hope this helps!

finlep [7]

The video game is on 35% discount.

Step-by-step explanation:

Cost of video game = $50

Price on sale = $32.50

Amount of discount = Original price - price on sale

Amount\ on\ discount = 50-32.50\\Amount\ on\ discount= \$17.5

Percentage = \frac{Dicount\ Price}{Original\ Price}*100

Percentage=\frac{17.5}{50}*100\\Percentage=\frac{1750}{50}\\Percenatge=35\%

The video game is on 35% discount.

Rishi spent:
=2×3/4
=6/4hours

Kyle spent

As they both spent 6/4 hours,they spent equal time.
