Question

a: ( x-963) :5 = 236 + 456 

b: x-590:5+2369+78945

Answer 1

\(a)(x-963):5=236+456\) 

\((x-963):5=689\) 

\((x-963)=689.5\)

 \(x-963=3445\) 

\(x=3445+963\) 

\(x=4408\) 

\(b)x-590:5+2369+78945\) 

đề sai

Answer 2

\(a,\left(x-963\right):5=236+456\)
\(\left(x-963\right):5=692\)
\(x-963=692\times5\)
\(x-693=3460\)
\(x=3460+693\)
Vậy \(x=4153\)
