Fist, write the equation as you see it:

7x + 12 = 9x

Next you have to put all the x’s on one side, whenever you move a number from one side to another it changes its sign (if it’s + it becomes - and if it’s - it becomes +)

7x - 9x = -12

Next add the x’s together:

-2x = -12

Then you must divide the two negive number which leave you with:

x = 6

The answer is x = 6.

Hope this helps!:)

What is the answer to this 14-2y=​
yaroslaw [1]

Answer:

y=7

Step-by-step explanation:

Assuming that the equation is 14-2y=0

We need to isolate 'y' variable to obtain its value, to do that, lets start by subtracting -14 to both sides of equality sign,

14-2y=0 is now this: 14-14-2y=0-14, which is equals to -2y=-14

Now, lets continue by dividing by -2 both sides of equality sign.

We have this

-2y/-2=-14/-2

y=7

Thus, we've obtained the value for 'y' variable
