Question

tìm y

(2367 -y )-(2^10 -7)=15^2-20

Answer 1

\(\left(2367-y\right)-\left(2^{10}-7\right)=15^2-20\)

\(\left(2367-y\right)-\left(1024-7\right)=225-20\)

\(\left(2367-y\right)-1017=205\)

\(\Rightarrow2367-y=205+1017=1222\)

\(\Rightarrow y=2367-1222=1145\)

Answer 2

(2367-y)-(2¹⁰-7)=15²-10

(2367-y)-(1024-7)=215

(2367-y)-1017=215

2367-y=215 + 1017

2367-y=1232

y=2367-1232

y=1135

Answer 3

\(\left(2367-y\right)-\left(2^{10}-7\right)=15^2-20\)

\(\Rightarrow\)\(\left(2367-y\right)-\left(1024-7\right)=225-20\)

\(\Rightarrow\)\(\left(2367-y\right)-1017=205\)

\(\Rightarrow\)\(\left(2367-y\right)=205+1017\)

\(\Rightarrow\)\(2367-y=1222\)

\(\Rightarrow\)\(y=2367-1222\)

\(\Rightarrow\)\(y=1145\)
