7x+2=-12 solve?

7x2-12

#1

7x+2=-12

Answer:

7x+2=-12
by transposing rule
7x=-12-2
7x=-14
x=-14/7
x=-2

7x+2=-12

When we get an equation like this , we will need to solve for X, our goal is to isolate the variable.

7x+2= -12 …Step 1: subtract 2 from both sizes, because the 2 is added to
-2 -2… 7x and we need to get it to zero so +2 -2 = 0 , but
-------------- … whatever you do on one side must do the same .
7x =-14 … Step 2: Isolate the variable by multiplying or dividing, Since
— --- …7 is multiple to x , we divide by 7 so on both sides
7 7 … so we can get just x, 7 divided by 7 = 1 , 1 times x =
… x.
… Step 3: simply if need to, -14/7 which both the numerator and
x= -2 …denumerator which both have in common is a
… multiple of 7 , which will give us -2/1= -2
