Answer:

x=49

Step-by-step explanation:

2(3x+1)=3(2−x)

Step 1: Simplify both sides of the equation.

2(3x+1)=3(2−x)

(2)(3x)+(2)(1)=(3)(2)+(3)(−x)(Distribute)

6x+2=6+−3x

6x+2=−3x+6

Step 2: Add 3x to both sides.

6x+2+3x=−3x+6+3x

9x+2=6

Step 3: Subtract 2 from both sides.

9x+2−2=6−2

9x=4

Step 4: Divide both sides by 9.

9x9=49

x=49

After I read the equation, I remembered that anything to the power of 1 is itself. so f(x)=2-9

2-9= -7

therefore, f(x)= -7

if x=1, then the f(x) must be Y

<u><em>therefore, your answer should be y= -7</em></u>

If 2 = 6, 3 =12, 4 = 20, 5 = 30, 6 = 42 then 9 = ?

At first you may get confused but look at those numbers carefully :)

as you see first result is divisible buy one of the product (second product in all cases is unknown)
so let's check where it will lead us :)

$6/2=3$

$12/3=4$

$20/4=5$

$30/5=6$

$42/6=7$

Now you can clearly see that every number was multiplied by number 1 higher than itself.
$2*(2+1)=6$

$3*(3+1)=12$

$4*(4+1)=20$

etc...

it means that after equation sign there should be $90$ because

$9*(9+1)=90$ :)

Help! Which step is incorrect!

monitta

Step (1) is incorrect. To divide by a number means to multiply by the reciprocal. In step (1) they did not convert the polynomial into its reciprocal.
