Answer:
The equivalent expression for x+9=10 is x=1.
Step-by-step explanation:
We have a statement i.e. x+9=10
We need to find an equivalent statement for the above statement.
If we subtract 9 on both sides of the above statement,
x+9-9=10-9
We know that, 9-9=0 and 10-9 =1
x+0=1
x=1
So, the equivalent expression for x+9=10 is x=1.
