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

If the temperature after 4.4 degree drop was -2.5 degrees Celsius what was the temperature at noon

Lostsunrise [7]

Answer:

1.9°C

Step-by-step explanation:

Let X be the temperature at noon and -2.5°C be the current temperature after the drop.

-We calculate temperature at noon as:

$\bigtriangleup =t_o-t_n\\4.4=X--2.5\\\\X=4.4-2.5\\\\=1.5\textdegree C$

Hence, the temperature at noon was 1.9°C

-2x-9y=-25 -4x-9y=-23

goldfiish [28.3K]

So to start this off you would add 9y to both sides of the equation and then you regroup it which gives you −2x=−25+9y and then you regroup the terms and get -2x=9y-25 and then you dived both sides by -2 and get x=9y-25/-2 then you simplify and so on

but at the end you should get x=-1 and y =3
