Answer 3

To solve the equation $a - 45 \times 2 = 900$, follow these steps:

Step 1: Simplify the expression on the left side of the equation. $a - 45 \times 2 = a - 90$

Step 2: Now, we have the equation: $a - 90 = 900$

Step 3: Isolate the variable $a$ on one side of the equation. To do this, add 90 to both sides: $a - 90 + 90 = 900 + 90$

This simplifies to: $a = 990$

The solution to the equation is $a = 990$.
