Question

Tìm x,biết :

2 + 5 + 3 = x - 3

5 + 25 = x X 6

Answer 1

\(2+5+3=x-3\)

\(=10=x-3\)

\(\Rightarrow x=10+3=13\)

\(5+25=x\cdot6\)

\(=30=x\cdot6\)

\(\Rightarrow x=30:6=5\)

Answer 2

2+5+3=x-3

  10 = x-3

x-3 = 10

x    = 10+3 = 13

5+25 = x.6

  30 = x.6

x.6 = 30

x  = 30 : 6 = 5

Answer 3

2 + 5 + 3 = x - 3

=> x - 3 = 2 + 5 + 3

=> x - 3 = 10

=> x      = 10 + 3

=> x      = 13

5 + 25 = x X 6

=> x X 6 = 5 + 25

=> x X 6 = 30

=> x       = 30 : 6

=> X       = 5

Answer 4

2+5+3=x-3                                         5+25=X x 6

10=x-3                                               30=X x 6

x=10+3                                              X=30:6

x=13                                                  X=5

Answer 5

2 + 5 + 3 = x - 3

= 2 + 5 = x - 3 + 3  = x

= 2 + 5 = x

=  7 = x

25 + 5 = x X 6

30 = x X 6

30 : 6 = x

5 = x
