Stephanie's mother is 30.

y-1=x/6

y = stephanie's age (6) and
x = Stephanie's mother's age (unknown)

let x= age of stephanie's mother
so
6= x/6 +1
subtracting 1 from both sides
5=x/6
cross mutiplying
x= 6*5 =30
i.e stephanie's mother's age is 30 years
Check
1/6th of stephanie's mother's age is 1/6 of 30 =5
stephanie's age is 1 year more than that = 5+1 =6 which is given
so answer is correct

x / 6 + 1 = 6

x / 6 + 1 - 1 = 6 - 1

x / 6 = 5

6(x/6) = 6(5)

x = 30

The answer is; Stephanie's Mother is 30 years old

x = mother's age
x/6 +1 = 6
x/6=5
x=30 = mother's age

Check: 1/6 * 30 = 5
6 is 1 year more than 5 which is 1/6 of mother's age.

S=6
6=1+(1/6)M
multiplying by 6
36=6+M
adding -6
M=30
the mother is 30 yr.old

Let mother's age is x
6=1+x/6
x/6=5
x=30

Setting S to be Steph's age and M to be her mother's age...

S=(1/6)M+1

If S is 6...

6=(1/6)M+1
5=(1/6)M
30=M

her mother's age is x, so:

6=1+(1/6)*x

6=1+(x/6)
6*6=1+x
x=6*6-1
X=35

So her mother is 35 years old.

6 = 1 + (x/6)
You can solve for that, which would break down to
5 = x/6
5*6 = x
30 = x
