Question

What is the inverse of the operation x-3=7?

Answer 1

we know that

addition and subtraction are inverse operations:

so

we have

x-3=7

7+3=x ------> inverse operation

we have

x-3=7

solve for x -----> that means isolate the variable x

adds 3 both sides

x-3+3=7+3

simplify left side

x=10
