Question

Solve the equation, justify each step with an algebraic property.
-4+-17+x.

Answer 1

–21 + x

Step-by-step explanation:

Step 1: Given expression: –4 + (–17) + x

Step 2: In the algebraic property, positive × negative = negative

So, –4 + (–17) + x = –4 – 17 + x

Step 3: Add two negative numbers, the result will be sum with minus sign

–4 – 17 + x = –21 + x

Hence, –21 + x is the required equation.
