Question

( 4x + 5 ) : 3 -121 :11 =4

Nhanh lên mình đang vội lắm !

Answer 1

( 4x + 5 ) : 3 - 121 : 11 = 4

( 4x + 5 ) : 3 - 11 = 4

( 4x + 5 ) : 3 = 4 + 11

( 4x + 5 ) : 3 = 15

4x + 5 = 15 x 3

4x + 5 = 45

4x = 45 - 5

4x = 40

x = 40 : 4

x = 10

Answer 2

( 4x + 5) : 3 - 12 : 11 = 4

( 4x + 5) : 3 - 12 = 4 x 11 = 44

( 4x + 5) : 3 = 44 + 12 = 56

4x + 5 = 56 x 3 = 168

4x = 168 - 5 = 163

x = 163 : 4

x = ....

Answer 3

\(\left(4x+5\right):3-12:11=4\)

\(\left(4x+5\right):3-12:11=4+\frac{12}{11}\)

\(\left(4x+5\right):3=\frac{56}{11}\)

\(\left(4x+5\right):3=\frac{56}{11}\cdot3\)

\(4x+5=\frac{168}{11}\)

\(4x=\frac{168}{11}-5\)

\(4x=\frac{113}{11}\)

\(x=\frac{113}{11}:4\)

\(x=\frac{113}{44}\)

Answer 4

x=113/44
