Respuesta :
Let x - 2 = the answer
then x = the answer + 2
Therefore
5(the answer + 2) - 10 = 25 Add 10 to both sides
5(answer + 2) = 35 Distribute 5 over the terms in the parentheses on the left side
5*answer + 10 = 35 Subtract 10 from both sides
5*answer = 25 Divide by 5 on both sides
answer = 5
And that's the "answer' for x - 2
Hope that help!
