Hi there!

Answer:

a=10 and 10=a

Explanation:

Addition property of equality is adding the same number to both sides of an equation does not change the equation.

switch sides.

-15+a=10-15

subtract by the numbers. subtract it's should be the found in the difference between the numbers, fractions, and spent.

10-15=-5

-15+a=-5

add 15 both sides of an equation.

-15+a+15=-5+15

simplify.

-5+15=10

15-5=10

10+5=15

15-5=10

a=10 and 10=a

Hope this helps!

-Charlie

Have a great day!
