Write your own real world situation that could be modeled by y=10+4x

First, do you mean y=(1/20)x or 1/(20x)?

It makes a big difference!

Assuming that the first choice is the correct one, x could represent the total price of purchases, and y could represent the amount of sales tax (1/20 is 5% tax).

Step-by-step explanation:

d. 8 that's the correct answer

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
