5
Step-by-step explanation:
Given: 5^3– 10^2 = X(8 – 2) + 2X – 3X
Solving the equation to find the value of x.
⇒![5^{3} -10^{2} = x(8-2)+2x-3x](/tpl/images/0460/4486/7af15.png)
Using the distributive property of multiplication, multiplying x with 8 and -2
⇒![125-100= 8x-2x+2x-3x](/tpl/images/0460/4486/83aeb.png)
cancelling out -2x and 2x
⇒![25= 8x-3x](/tpl/images/0460/4486/747ac.png)
⇒![25= 5x](/tpl/images/0460/4486/d5f7e.png)
Multiplying both side by 5
⇒ x=![\frac{25}{5}](/tpl/images/0460/4486/c6d97.png)
∴ x= 5
Hence, the value of unknown is 5.
