Question

cho hoi nha

72+(150+x) . 4 =100

x =???

giai luon

 

Answer 1

72 + (150 +x) *4 = 100

(150 +x) *4 = 100 - 72

(150+x) *4 = 28

150 +x = 28 :4

150 +x = 7

x= 150 -7

x=143

Answer 2

72+(150+x).4=100

\(\Rightarrow\)72+600+4x=100

\(\Rightarrow\)672+4x=100

\(\Rightarrow\)4x=100-672

\(\Rightarrow\)4x=-572

\(\Rightarrow\)x=-143

Answer 3

72 + ( 150 + X ) x 4 = 100

( 150 + X ) x 4 = 100 - 72

( 150 + X ) x 4 = 28

( 150 + X ) = 28 : 4

( 150 + X ) = 7

X = 150 - 7

X = 143
