Hey there!
When solving a equation like this we always want to start with the distributive property.
4 ( 9x + 7 ) = x - 4
36x + 28 = x - 4
Next, we want to subtract 28 from both sides.
36x + 28 = x - 4
-28 -28
Now, our equation will look like this:
36x = x - 32
Our next step is to subtract x from both sides.
36x = x - 32
-x -x
your equation will now look like this:
35x = -32
The final step is to divide -32 by 35.
-32 / 35 = -0.91
Hope this helps.
