Hello,

$x^2-2x-27=-5x+1\\

x^2-2x+5x-27-1=0\\

x^2+3x-28=0\\

x^2+7x-4x-28=0\\

x(x+7)-4(x+7)=0\\

(x+7)(x-4)=0\\

x=-7\ or\ x=4\\

Solve the following equation. 36 − 3|x| = 18 A. x = 6 or x = -18 B. x = 6 or x = -6 C. x = 18 or x = -6 D. x = 18 or x = -18

Answer:

A: x=6

Step-by-step explanation:

If x is equal to 6, then -3 multiplied by 6 would be equal to 18.

Then you take that 18 and subtract it from 36.

36-18=18
