Let's use simultaneous equations for this question.

y will be the larger number and x being the smaller number.

The sum is 45 so: x + y = 45 (eq1)

The larger number is 3 less than twice the smaller number. Changing this to an equation becomes

y = 2x - 3 (eq2)

Let's use substitution and substitute eq2 into eq1

x + (2x - 3) = 45

Simplify

3x - 3 = 45

Move the -3 to the right hand side, this will ch... more
