First way:
Solution:
152 - 58 = 94 reserves and monuments, without taking into account the difference (if equally)
94 : 2 = 47 parks
47 + 58 = 105 reserves
Answer: 47 parks; 105 reserves.
Second way:
Let x parks in USA
x + 58 reserves in the USA
write the equation:
x + (x + 58) = 152
x + x + 58 = 152
2x + 58 = 152
2x = 152 - 58
2x = 94
x = 94: 2
x = 47 - parks
47 + 58 = 105 reserves
