Question

Solve for a in the equation a – 17 = 42

Answer 1

Hi there! :)

Answer:

a=59

*The answer must have a positive sign.*

Explanation:

Lesson: Addition property of equality

`a+c=b+c`

First, you add by 17 from both sides of an equation.

`a-17+17=42+17`

And then, you simplify and solve. You can also add by the numbers from left too right.

`42+17=59`

Final answer is a=59

Hope this helps! :)

Have a great day!
