Question

(X+5)x19:13=5,7

Answer 1

\(\left(x+5\right)\cdot19:13=5.7\)

\(\left(x+5\right)\cdot19=5.7\cdot13\)

\(\left(x+5\right)\cdot19=74.1\)

\(x+5=74.1:19\)

\(x+5=3.9\)

\(x=3.9-5\)

\(x=-1.1\)

Answer 2

\(\left(x+5\right)\times19\div13=5,7\)

\(\Rightarrow x\times19\div13=5,7\)

\(\Rightarrow x=5,7\div19\times13\)

\(\Rightarrow x=3,9\)

\(\Rightarrow x=3,9-5\)

\(\Rightarrow x=-1,1\)
