You need to combine like terms. So first you have to add the negative number which are -4x and -6x which equals -10x. So the problem is now -20=-10x. Finally use inverse operation to get x by itself. So x=2.
Watch carefully . . . this could get really tricky:
-20 = -4x -6x
Do you see the -4x and the -6x on the right side ? I'll bet if it said (4 negative cows) and (6 negative cows), you'd know right away that you could combine them into (10 negative cows).
-4x - 6x = -10x
So now the equation is -20 = -10x
Multiply each side by -1 : 20 = 10x
Divide each side by 10 : 2 = x
and there you have it.
To solve the equation -20 = -4x - 6x, combine like terms to get -20 = -10x. Then, divide by -10 to isolate x, resulting in x = 2. You can verify this solution by substituting x back into the original equation.
