Answer:

x=-1

Step-by-step explanation:

The first thing we can do is subtract 3x from both sides (it makes solving the equation easier if you get rid of the variable first).

3x+6=4x+7

-3x -3x

6=x+7

All we need to do now is subtract 7 on both sides.

6=x+7

-7 -7

-1=x or x=-1 (they both mean the same thing!)

Hope this helps!! Have a wonderful day c:

What is the value of x in the equation (x + 12) = (x + 14) – 3?

mariarad [96]

Answer:

No solution or x ∈ ∅

Step-by-step explanation:

We have given the equation ⇒ x+12 = (x+14) -3

if we solve this equation ⇒ x+12 = x+14-3

⇒x+12= x+11

⇒12 ≠ 11

which state that x ∈ ∅

i.e. there is no value of x which make the equation true

therefore, No solution

If this is true then what does K equal to? Write as an inequality. plz help me. you will be greatly appreciated.

Scrat [10]

Answer:

K = (2v)/2

Step-by-step explanation:

1. Multiply both sides by 2/n

Now: (2v)/n = b + K

2. Subtract k from both sides

Now: (2v)/n - b = K
