Can someone please help me with this(Will mark branliest) :)

X=3 (hope this helps)

Step-by-step explanation:

So what you want to see if they are equal (in this case they are) so we have 10 plus 12x and we also have 15x plus 1  

10 + 12x = 15x + 1 (solve for x)

-15x + 12x=1 - 10

-3x = -9

x=3

12/11c

or

12

c

11
