I need help with solving an equation and solution for this someone please

x = -2

Step-by-step explanation:

Picture attached, shows a weighing scale in the balanced form,

So weight of elements on the left = Weight of the elements on the right

Left side of the scale = weight of x + weight of 1

                                   = x(2) + 1(6)

                                   = 2x + 6

On the right side of the scale = Weight of (-x) + weight of (-1)

                                                 = (-x)(2) + (-1)(2)

                                                 = -2x - 2

Since, both the sides are balanced,

Therefore, equation which models the situation is,

(2x + 6) = -(2x + 2)

(2x + 6) + (2x + 2) = 0

4x + 8 = 0

4x = -8

x = -2

the answer is c

hope this !
