Question

What is the solution to the equation 3x + 2(x − 9) = 8x + x − 14? (1 point)

Answer 1

Answer:

B. -1

Step-by-step explanation:

STEP 1: Simplify 3x+2(x−9).

$5x-18=8x+x-14$

STEP 2: Add 8x and x.

$5x-18=9x=-14$

STEP 3: Move all terms containing x to the left side of the equation.

$-4x-18=-14$

STEP 3: Move all terms not containing x to the right side of the equation.

$-4x=4$

STEP 4: Divide each term by −4 and simplify.

$x=-1$
