Answer:
6
Step-by-step explanation:
expand
x-7= 1/4x-10/4
3/4x=18/4
multiply 4 on both sides to get rid of the denominator
3x=18
x=6
check work by substituting
6-7= 1/4(6-10)
-1= 1/4(-4)
-1=-1
they are equal, so it's correct
b is not a function
To be a function there must be a one to one correspondence.
Each x must only go to one y
b has an x that goes to two different y's
1 goes to 5 and 13. That makes it a relation not a function
