Question

a) 500 + 500 + 500 = x

b) x + x + x = 15

c) 50 + 50 = x . 50

Answer 1

a) 500 + 500 + 500 = x

1500 = x

=> x = 1500

Answer 2

b) x + x + x = 15

3. x = 15

x = 15 : 3

x = 5

Answer 3

c) 50 + 50 = x . 50

100 = x . 50

100 : 50 = x

2 = x

=> x = 2

Answer 4

a) \(500+500+500=x\)

\(\Rightarrow1000+500=x\)

\(\Rightarrow1500=x\)

Vậy \(x=1500\)

b) \(x+x+x=15\)

\(\Rightarrow3x=15\)

\(\Rightarrow x=15:3\)

\(\Rightarrow x=5\)

Vậy \(x=5\)

c) \(50+50=x.50\)

\(\Rightarrow100=x.50\)

\(\Rightarrow x=100:50\)

\(\Rightarrow x=2\)

Vậy \(x=2\)

Answer 5

a) 500 + 500 + 500 = x

=> 500 . 3 = x

=> 1500 = x

Vậy x = 1500

b) x + x + x = 15

=> x . 3 = 15

=> x = 15 : 3

=> x = 5

Vậy x = 5

c) 50 + 50 = x . 50

=> x . 50 = 50 + 50

=> x . 50 = 100

=> x = 100 : 50

=> x = 2

Vậy x = 2
