Answer:
<h3>Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)</h3>
Step-by-step explanation:
Given the expression
- 2 (x + 3) = - 10
The first step in solving the expression is to multiply both sides by -1/2 as shown;
-1/2(-2)(x+3) = -1/2(-10)
(x +3) = 1/2(10)
x + 3 = 5
x = 5-3
x = 2
Hence the correct option is Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)
Answer:

Step-by-step explanation:

So the eqn becomes

AND this equal to

Hence the variable x has 0 as its coefficient.
