Answer:
10 =x
Step-by-step explanation:
f(x) = x-7
Let f(x) = 3
3 = x-7
Add 7 to each side
3+7 = x-7+7
10 =x
Answer:
x=92 y=23
Step-by-step explanation:
Let them be x and y respectively
so given
x-y=69
and
x/y=4 x=4y
so we can write
x-y=69
as
4y-y=69 3y=69 y= 69/3 = 23
now y is 23
so putting in any equation will give the value of x
so
x-23=69 x=92
1/6 is the answer. Good luck!
