Question

2087-x /27=2015 và bài  này nữa 45*(463+x)=44955

Answer 1

Bài 1 :

\(\frac{2087-x}{27}=2015\)

\(2087-x=2015.27\)

\(2087-x=54405\)

\(x=2087-54405\)

\(x=-52318\)

B2 :

45(463+x)=44955

463+x=44955:45

463+x=999

x=999-463

x=536

Answer 2

Bài 1 :

$\frac{2087-x}{27}=2015$2087−x27 =2015

$2087-x=2015.27$2087−x=2015.27

$2087-x=54405$2087−x=54405

$x=2087-54405$x=2087−54405

$x=-52318$x=−52318

B2 :

45(463+x)=44955

463+x=44955:45

463+x=999

x=999-463

x=536
