8x+10x=14-45-5
18x=-36
x=-2

8x - 14 = -10x - 45 - 5
8x + 10x = 14 - 50
18x = -36
x = -36/18
x = -2

You can use the idea of the scale to solve the problem or by using algebra.
I will just explain with algebra.
8x-14=-10x-50
Add 10x to each sides
18x-14=-50
Add 14 to each sides
18x=-36
Divide by 18 to each sides
x=-2.

Easy: -45-5 is 50
8x-14=-10x-50
36=2x
x=18
