Answer:
a = 5
Step-by-step explanation:
If it's easier for you, you can replace n(a) with y and put a as x.
Now the equation is y = 7x + 4.
It asks you to put in 39 as y.
39 = 7x + 4.
To solve this, the goal is to isolate the variable on one side. The first step I see is to subtract the 4 from both sides.
35 = 7x
Now divide both sides by 7 and we're done!
5 = x
Answer:
No.
Step-by-step explanation:
If you insert 1 as x, you get 
. This is not true.
Hope it helps!
Step-by-step explanation:
First, distribute the outside numbers into the parentheses:
5*x+5*-12+6=3*2x+3*-7
5x-60+6=6x-21
Combine like terms
5x-54=6x-21
Add 21 to both sides
5x-33=6x
Subtract 5x from both sides
you wind up getting x=-33
x=-33
you can check to make sure that's the correct answer but simply plugging in -33 for x and checking to make sure both sides of the equation are equal:
-33-12=-45*5=-225+6=-219
-33*2=-66-7=-73*3=-219
So, yes, x equals -33
