Which is the solution of the equation a + 2 = 10? A. a = 2

B. a = 5

C. a = 8

D. a = 12​

Hey there!

a + 2 = 10

SUBTRACT 2 to BOTH SIDES

a + 2 - 2 = 10 - 2

CANCEL out: 2 - 2 because that gives you 0

KEEP: 10 - 2 because that helps solve for the a-value

10 - 2 = a

10 - 2 = 8

Option C. a = 8

Good luck on your assignment and enjoy your day!
