Here is an equation. 2( x + 12) = 4x - 6.
goblinko [34]

Answer:

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

2 ( x+12 ) = 4x − 6

Step 1: Simplify both sides of the equation.

2 (x+12) = 4x − 6

(2) (x) + (2) (12) = 4x + −6 (Distribute)

2x + 24 = 4x + −6

2x + 24 = 4x − 6

Step 2: Subtract 4x from both sides.

2x + 24 − 4 x = 4x − 6 − 4x

−2x + 24 = −6

Step 3: Subtract 24 from both sides.

−2x + 24 − 24 = −6 −24

−2x = −30

Step 4: Divide both sides by -2.

−2x  / −2  =  −30  / −2

x=15

Answer:

x=15

What is the answer to 8(2× - 6) =96​
Arisa [49]

Answer:

the answer is 3

x= 3

Step-by-step explanation:

8(2× - 6) =96​

multiply 8 on the right side of equation we get

16x -48 = 96

16x= 96-48

16x = 48

divide by 16 on both side we get

simplify

16x / 16 = 48 / 16

x = 3

So that the value of x we get after the equation solved is x = 3

hopefully it will be brainliest for you

thank you !

What’s the inverse equation? And how you solved it step by step please!
Korvikt [17]

Answer:

The inverse is (x^2-5)/2

Step-by-step explanation:

y =sqrt(2x+5)

Exchange x and y

x = sqrt(2y+5)

Solve for y

Square each side

x^2 = (sqrt(2y+5))^2

x^2 = 2y+5

Subtract 5 from each side

x^2 -5 = 2y-5+5

x^2 -5 = 2y

Divide each side by 2

(x^2-5)/2 = 2y/2

(x^2-5)/2 = y

The inverse is (x^2-5)/2
