Question

What is heights of table, cat and tortoise

Answer 1

From picture 1:

Table + cat - tortoise = 170

From Picture 2:

Table - cat + tortoise = 130

So putting the 2 equations together:

Table + cat - tortoise = 170 -------------------- [ 1 ]

Table - cat + tortoise = 130 -------------------- [ 2 ]

[ 1 ] + [ 2 ] :

2 Tables = 170 + 130

2 Tables = 300

1 Table = 300 ÷ 2  = 150 cm

Answer: The height of the table is 150 cm.

*Note: There is not enough information to find the height of the cat or the tortoise.

Answer 2

NOTE - Question is lack of image which is incomplete.

I'm Answering here along with the image.

Picture (1) -

Table + cat - turtle = 170 cm --------- ( 1 )

Picture (2) -

Table - cat + turtle = 130 cm ---------- ( 2 )

Adding Two Equations we get -

2 Tables = 170 + 130

2 Tables = 300

1 Table = 300 ÷ 2 = 150 cm .

1 Table = 150 cm .
