2. In the equation 5(x - 3) = 25, what should you do after using the Distributive Property?​
son4ous [18]

Answer:

umm... This how I learned from the chapter simple equation. Hopefully helps

Step-by-step explanation:

5(x - 3) = 25  we have to find the value of 'x'

so transpose 5 x to the other side = (x - 3) = 25 divided by 5 becuz it was multiplication on the other side so it is equal to = (x - 3) = 5

Now we transpose -3 which is equal to = x = 5 + 3 = 8

so, <u>x = 8</u>

<u />

<u>hopefully it helps!!!!!!!</u>
