Final answer:
To solve the linear equation 6x+20=100, subtract 20 from both sides and then divide by 6 to isolate x, giving the solution x = 13.33.
Step-by-step explanation:
The equation 6x+20=100 is a linear equation from the field of mathematics. To solve for x, you need to isolate the variable on one side of the equation. Start by subtracting 20 from both sides to get 6x = 80. Then, divide both sides by 6 to get x = 80/6, which simplifies down to x = 13.33. The solution to the equation is x = 13.33.
