Question

please answer this question​

Answer 1

$\frac{21x-8x}{12}=\frac{4x}{3}$

$\frac{13x}{12}=\frac{4x}{3}$

13x=16x

13x−16x=0

−3x=0

x=0

Check answer

$\frac{21\times 0-8\times 0}{12}=\frac{4\times 0}{3}$

$\frac{0-8\times 0}{12}=\frac{4\times 0}{3}$

$\frac{0-0}{12}=\frac{4\times 0}{3}$

$\frac{0}{12}=\frac{4\times 0}{3}$

$\frac{0}{12}=\frac{0}{3}$

$0=\frac{0}{3}$

$0 = 0$
