What is the answer / how do i answer

25 = x + 7

answer should be x = 18.

Step-by-step explanation:

25 = x + 7

we can also write it as

x + 7 = 25

as we see 7 is positive (+) on LHS (left hand side) so if we move it to RHS (right hand side) the sign will change so the equation will be:

x = 25 - 7

now just simplify it:

x = 18.

Just subtract 7 from 25. it is 18
