Let the Catapult Shape be 'X', Quiver of Arrows be 'Y' and the Yacht be 'Z'

So the first image equation can be rewritten as X + X + X = 75 => 3X = 75 => X = 25

So the second image equation can be rewritten as X - Y + Z = 21 => 25 - Y + Z = 21 => -Y+ Z = 21-25 => Z - Y = -4

So the third image equation can be rewritten as  Y + 2Z = 7

Adding the second and third equation gives Z - Y + Y + 2Z = -4 + 7 => 3Z + 0Y = 3 => 3Z = 3 => Z = 1

Substituting value of Z in third equation gives Y + 2*1 = 7 => Y + 2 = 7 => Y = 7 - 2 => Y = 5

The Fourth image equation which is to be evaluated can be rewritten as Z + Y * X = ?

Substituting obtained values for X, Y, Z and applying BODMAS rule (do multiplication before addition here) gives

1 + 5 * 25 = 1 + 125 = 126

126 is hence the value of the equation.

1 + 4 x 25= 101

Mathematical rule, first the multiplications then the additions
