ANSWER:-
The first picture , we can translate into the following equation.
we have,
Table + cat - turtle = 170 cm --------- ( 1 )
The second picture will correspond to the equation
Table - cat + turtle = 130 cm ---------- ( 2 )
So now, from the two equation we need to solve for the height of the table
Adding the two equations
we get,
Table + cat - turtle + Table - cat + turtle = 170 + 130
2 Tables = 170 + 130 ( The two variabli are cancel)
=> 2 Tables = 300
=> 1 Table = 300 ÷ 2 = 150 cm .
=> 1 Table = 150 cm .
Hence the height of the table is 150 cm
