To solve the equation, we need to simplify both sides and isolate the variable x.

Starting with the left side of the equation:
100 - (x - 3) / 2

We can simplify the expression inside the parentheses by distributing the negative sign:
100 - x + 3 / 2

Next, we can simplify the expression inside the parentheses by dividing 3 by 2:
100 - x + 1.5

Now, let's move to the right side of the equation:
7^2 - 1^10

Simplifying the exponents:
49 - 1

Now, we can rewrite the equation as:
100 - x + 1.5 = 49 - 1

Combining like terms:
99.5 - x = 48

To isolate x, we can subtract 99.5 from both sides:
-x = 48 - 99.5

Simplifying:
-x = -51.5

Finally, we can solve for x by multiplying both sides by -1:
x = 51.5

Therefore, the solution to the equation is x = 51.5.
