Answer:
3 + 4x = 36----->No
(4.3)+(4 . x)= 36------>Yes
4(3 + x)= 144--------->No
3+ x = 9-------> Yes
12 + x = 36------>No
12 + 4x = 36------->Yes
Step-by-step explanation:
The given equation is

A correct first step is to expand the LHS to get:

Or to divide through by 4 to get:

Or just distribute to get:

The slope is 1 and there is no y intercept.

Answer:
12 + 4x
Step-by-step explanation:
To solve this you would have to use the distributive property.
The problem would basically go like this.
4 (3+x)
(Distribute)
(4x3) (4 x X)
4x3 = 12, 4 x x = 4x
So the answer would be 12 +4x
Hope this helps :)
