Answer:

18

Step-by-step explanation:

  • we can use the variable x to represent the number since it's currently unknown
  • seven more than the number can be represented as x + 7
  • we can find the sum of both by adding them

x + x + 7 = 43

2x + 7 = 43

     -7     -7

2x = 36

  • we divide by 2 on both sides to isolate x

x = 18
