Question

Translate into verbal phrase
a/-2-10=3

Answer 1

a = 15

Explanation:

Step 1: Group the constant terms on the left-hand side:

-2 - 10 = -12

Step 2: Form a modified equation

a/ - 12 = + 3

Step 3: Group constants:

We need to group our constants -12 and 3. To do that, we add 12 to both sides

a/ - 12 + 12 = 3 + 12

Step 4: Cancel 12 on the left side:

a = 15
