2(x-6)=3(x+3)

Let's solve your equation step-by-step.

2(x−6)=3(x+3)

Step 1: Simplify both sides of the equation.

2(x−6)=3(x+3)

Simplify: (Show steps)

2x−12=3x+9

Step 2: Subtract 3x from both sides.

2x−12−3x=3x+9−3x

−x−12=9

Step 3: Add 12 to both sides.

−x−12+12=9+12

−x=21

Step 4: Divide both sides by -1.

−x/−1=21/−1

x=−21

Answer:

x=−21

brilliants [131]

Answer:

short story has 32 pgs

novel has 416 pgs

Step-by-step explanation:

a novel (N) has 13 times as many pages as a short story (x) so, N = 13X

total pages is the equation N + x = 448

plug the equation for N into this

13x + x = 448, combine like terms

14x = 448, divide both sides by 14

x = 32. so now we know that the short story has 32 pages. subtract that from 448. and the novel has 416 pages.
