Question

Which of the following best describes the solution to the equation below? 21​(10x−8)=5x

a. x=6
b. x=8
c. x=10
d. x=12

Answer 1

The solution to the equation 21​(10x−8)=5x is 0.82. None of the given options is answer.

Explanation:

To solve the equation 21​(10x−8)=5x, we first expand the left-hand side of the equation:

210x - 168 = 5x

Then, we simplify the equation by moving all the terms to one side:

205x = 168

Finally, we solve for x by dividing both sides by 205:

x = 168/205 ≈ 0.82
