>>13122444ngmi. the exact height of the cat and turtle don't change the measurements, only their difference in height
Cat + Table - Turtle = 170
Turtle + Table - Cat = 130
e.i. if A=B and C=D, then A+C=B+D.
collect like terms and you will see 2*Table = 300 => Table = 150cm
the galaxy brain way to solve this problem is to recognize the first measurement is the table plus the cat and turtle's difference in height, and the second measurement is the table minus their diference in height, which means the table height is equidistant from 170 and 130 on the number line, and hence just the average of the 2 measurements
