The correct answer is X+6?
X-6=6?
x= 12?
x+6= 12+6= 18
Solve the equation and write the inspection process:
1. Substitute the unknown value into the original equation.
2. What's on the left? Is it right?
3. Judge whether the unknown value is the solution of the equation.
For example: 4.6x=23
Solution: x=23÷4.6
x=5
Check:
Substituting x = 5 into the equation, we get:
Left =4.6×5
=23= Right
So x=5 is the solution of the original equation.
