Answer:

18

Step-by-step explanation:

Let x be the smaller number. The larger number would be...

x+7 as the question states their difference is 7.

We can use this to set up an equation:

x+x+7=43

Combine like terms

2x+7=43

Subtract 7 from both sides

2x=36

Divide both sides by 2

x=18

The smaller number is 18
