-4x-6x = -20
-10x = -20
Divide both sides by -10 rembering that a minus divided into a minus the result is positive:
x = 2
divide 20 by 10 which equals 2 the times 2 by 2 which equals 4
x = 5
(20 - x)/5
36 -20 = 16
To solve for x, we'd have to know what this expression equals.
25
20
6x-20 = 8x 6x-8x = 20 -2x = 20 x = -10

-7m + 20 = -17m - 1010m = -30m = -3
The question cannot be answered because, as it appears, it makes no sense.
math order operation is : x : + - so: 6-4x6x-8x2 = 6 - [4 x 6 x (-8) x 2] = 6 - (-384) = 390
