Answer:
x=4
Step-by-step explanation:
Based on the given conditions, formulate:
x+8=3×x
Rearrange unknown terms to the left side of the equation:
x-3x=-8
Combine like terms:-2x=-8
Divide both sides of the equation by the coefficient of variable:x=-8/-2
Rewrite the fraction:8/2
Cross out the common factor:x=4
get the result:x=4
Answer: 4
