Answer:
B. -1
Step-by-step explanation:
STEP 1: Simplify 3x+2(x−9).
[tex]5x-18=8x+x-14[/tex]
STEP 2: Add 8x and x.
[tex]5x-18=9x=-14[/tex]
STEP 3: Move all terms containing x to the left side of the equation.
[tex]-4x-18=-14[/tex]
STEP 3: Move all terms not containing x to the right side of the equation.
[tex]-4x=4[/tex]
STEP 4: Divide each term by −4 and simplify.
[tex]x=-1[/tex]
