To solve the equations:
1) X - 42 = 38Add 42 to both sides:X = 80
2) 16 + X = 51Subtract 16 from both sides:X = 35
3) 900 - X = 200Subtract 900 from both sides:-X = -700Divide by -1 to solve for X:X = 700
So, the solutions are:X = 80, 35, 700
To solve the equations:

Add 42 to both sides:
X = 80
2) 16 + X = 51
Subtract 16 from both sides:
X = 35
3) 900 - X = 200
Subtract 900 from both sides:
-X = -700
Divide by -1 to solve for X:
X = 700
So, the solutions are:
X = 80, 35, 700
