is the x before the 21 is multiplication then I need a value for x to solve, but for the sake of an answer I will assume it's 6x-12=21 6x-12=12 +12 +12 6x=24 /6 /6 x=4 is the x before the 21 is multiplication then I need a value for x to solve, but for the sake of an answer I will assume it's 6x-12=21 6x-12=12 +12 +12 6x=24 /6 /6 x=4

What is -6x12 equals?
-72. every time you divide or multiply negatives, two negatives = a positive. example: -8x-9= +72 -50 Divided by -5=10. if there is one negative and one positive, the answer is always negative. example: -8x5=-40 10 divided by -5=-2 ~denominatin

How do you show that 2 sin squared x minus 1 divided by sin x minus cos x equals sin x plus cos x?
(2 sin^2 x - 1)/(sin x - cos x) = sin x + cos x (sin^2 x + sin^2 x - 1)/(sin x - cos x) =? sin x + cos x [sin^2 x - (1 - sin^2 x)]/(sin x - cos x) =? sin x + cos x (sin^2 x - cos^2 x)/(sin x - cos x) =? sin x + cos x [(sin x - cos x)(sin x + cos x)]/(sin x - cos x) =? sin x + cos x sin x + cos x = sin x + cos x
