Solve for X:
21(x+3)−8x=3
Let's solve the given equation 21(x+3)−8x=3.
First, distribute the 21 inside the parentheses:
21(x+3)=21x+21×3=21x+23.
Substitute back into the original equation:
21x+23−8x=3.
To eliminate the fraction, multiply every term by 2 to simplify:
2×(21x+23)−2×8x=2×3.
After clearing the fraction, the equation becomes:
x+3−16x=6.
Combine like terms involving x:
x−16x+3=6 simplifies to −15x+3=6.
Isolate x by subtracting 3 from both sides:
−15x=6−3.
This simplifies to −15x=3.
Finally, divide both sides by −15 to solve for x:
x=−153,
which simplifies to x=−51.
Therefore, the solution to the equation 21(x+3)−8x=3 is x=−51.
