Answer
{10}
Work Step by Step
x-7 = 3
Step 1: Add 7 on both the sides
x-7+7 = 3+7
Step 2: Simplify
x= 10
Now we check the proposed solution, 10, by replacing x with 10 in the original equation.
Step 1: the original equation x-7 =3
Step2: Substitute 10 for x
10 - 7 = 3
Step 3: Subtract 10-7 = 3
3=3
Since the check results in true statement, we conclude that the solution set of the given equation is {10}.
