The answer is 44.
Let star represent X , Square represent Y and triangle represent Z.
Taking the equation from Left most column,
3X + Y = 35 ---> 1
Taking the equation from the second row from the top
2X + 2Y = 50 ---> 2
Taking the equation from the third column from the left ,
X + 2Y + Z= 59 ---> 3
Solving 1 and 2 , value of X = 5 and Y = 20
Substituting X and Y in 3, value of Z = 14

The new equation for which the value to be found is = 2X + Y + Z === 44
