Question

Solve for a.

a + (−5) = 12

Answer 1

a=17

Explanation:

any number plus a negative number is basically subtracting the absolute value of the negative number. so 12 + 5 = 17

Answer 2

a = 17

Explanation:

a + (-5) = 12

Open the bracket;

a - 5 = 12

Add 5 to both sides

a - 5 + 5 = 12 + 5

Therefore,

a = 17
