Question

a)X * 6 +18=24

b)6 * x -12=36

c)x : 6 +15=20

d)54 : x +20=29

Answer 1

a)

x . 6 + 18 = 24

x . 6 = 24 - 18

x . 6 = 6

x = 6 : 6

x = 1

Vậy x = 1

b)

6 . x - 12 = 36

6 . x  = 36 + 12

6 . x  = 48

x = 48 : 6

x = 8

Vậy x = 8

c)

x : 6 + 15 = 20

x : 6 = 20 - 15

x : 6 = 5

x = 5 .6 

x = 30

Vậy x = 30

d)

54 : x + 20 = 29

54 : x = 29 -20

54 : x = 9

x = 54 : 9

x = 6

Vậy x = 6

Answer 2

a)X * 6 +18=24

X*6 = 24-18 

X*6 = 6 

X= 6:6 

X=1

b)6 * x -12=36

6*X= 12 +36 

6*X = 48 

X= 48 :6 

X= 8 

c)x : 6 +15=20

X:6 = 20-15 

X:6 = 5 

X= 5*6 

X=30

d)54 : x +20=29

54 :X = 29-20 

54 : X = 9 

X= 54 :9 

X= 6

Answer 3

a,\(X\times6+18=24\)

\(X\times6=24-18\)

\(X\times6=6\)

\(X=6:6\)

\(X=1\)

b,\(6\times x-12=36\)

\(6\times x=12+36\)

\(6\times x=48\)

\(x=48:6\)

\(x=8\)

c,\(x:6+15=20\)

\(x:6=20-15\)

\(x:6=5\)

\(x=5\times6\)

\(x=30\)

d,\(54:x+20=29\)

\(54:x=29-20\)

\(54:x=9\)

\(x=54:9\)

\(x=6\)
