Question

(x-1,3)+(x+2,5)+(x-3,8)=1,9

x/3+x/6+x/9=2\(\frac{1}{3}\)

x*2+3*x+4,2=10,2

Answer 1

( x - 1,3 ) + ( x + 2,5 ) + ( x - 3,8 ) = 1,9

x - 1,3 + x + 2,5 + x - 3,8 = 1,9

3x - 2,6 = 1,9

3x = 4,5

Answer 2

\(\frac{x}{3}+\frac{x}{6}+\frac{x}{9}=2\frac{1}{3}\)

\(\frac{6x}{18}+\frac{3x}{18}+\frac{2x}{18}=\frac{7}{3}\)

\(\frac{11x}{18}=\frac{42}{18}\)

\(\Rightarrow11x=42\)

\(\Rightarrow x=\frac{42}{11}\)

Answer 3

\(x\cdot2+x\cdot3+4,2=10,2\)

\(x\cdot\left(2+3\right)=6\)

\(x\cdot5=6\)

\(x=\frac{6}{5}\)
