Solve the equation for<br> x 3/4(x+21) = 10.5 <br> x =
MrRa [10]
<h3>✍️ Answer:</h3><h3>x=-\frac{294}{13}</h3>

✽✽✽✽

\frac{x\cdot \:3}{4\left(x+21\right)}=10.5

\mathrm{Multiply\:both\:sides\:by\:}4\left(x+21\right)

\frac{x\cdot \:3}{4\left(x+21\right)}\cdot \:4\left(x+21\right)=10.5\cdot \:4\left(x+21\right)

3x=42\left(x+21\right)

3x=42x+882

\mathrm{Subtract\:}42x\mathrm{\:from\:both\:sides}

3x-42x=42x+882-42x

-39x=882

\mathrm{Divide\:both\:sides\:by\:}-39

\frac{-39x}{-39}=\frac{882}{-39}

x=-\frac{294}{13}
