math order operation is : x : + - so: 6-4x6x-8x2 = 6 - [4 x 6 x (-8) x 2] = 6 - (-384) = 390
No, it is an equation. n+6 is an expression.

It is an equation and the value of x is 20
-2t = -10
k is the variable.
5x6 = 30 -10 = 20.
z = 20 (6x20) + (5x20) = 20
the answer is 33.333333333

Write out equation - 10y - 5x= - 20 Negate equation 10y + 5x = 20 Isolate y variable 10y = - 5x + 20 Divide equation by 10 y= -1/2x + 2
4x - 20 = -44x = 16x = 4
