Question

X + X *  1/4 : 2/7 + X : 2/9 = 255

Answer 1

\(x +x\cdot\frac{1}{4}\text{ : }\frac{2}{7}+x\text{ : }\frac{2}{9}=255\)

\(x+x\cdot0,25\text{ : }0,285714286+x\text{ : }0,222222222=255\)

\(x+x\cdot\left(0,25\text{ : }0,285714286\right)+x\text{ }\text{ : }0,222222222=255\)

\(x+x\cdot0,874999999+x\text{ : }0,222222222=255\)

\(x\cdot3\cdot\left(0,874999999\text{ : }0,222222222\right)=255\)

\(x\cdot3\cdot3,9375=255\)

\(x\cdot3=255\text{ : }3,9375\)

\(x\cdot3=64,7619048\)

\(x=64,7619048\text{ : }3\)

\(x=21,5873016\)
