Question

If 5x-10=25 what is the value of x-2

Answer 1

Divide the whole equation by 5. You should then get:

x - 2 = 5

Answer 2

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!
