Question

Which of the following steps indicates the addition property of equality while solving the equation –1 – 6x = x – 15? Question 4 options: A) x = 14∕2 B) –1 – 6x + 15 = x – 15 + 15 C) –1 – 6x = x – 15 D) 23 – 6x – 24 = x – 15

Answer 1

Answer:

B) -1-6 x +15 = x - 15 +15

Step-by-step explanation:

Explanation:-

Given equation is  –1 – 6 x = x – 15

By addition property of equality

                       ⇒     - 1 - 6 x + 15 = x - 15 +15

                      ⇒      - 6 x + 14  = x

subtracting 'x' on both sides ,we get

                       ⇒      - 6 x -x +14 =0

                        ⇒      - 7 x +14 =0

                         ⇒      -7 x = - 14

   Dividing '-7'  on both sides , we get

                                 x  = 2

The solution of given equation is    x  = 2
