Ok. So, if 8 pens cost £12. Then we would divide £12 by 8. Each pen costs £1.5.
So now we are going to multiply £1.5 and 10. £1.5*10=15.
The total of 10 pens is £15.
I hope this helps, if you need any additional help, just ask. I am here to help you as needed.
Is it supposed to be equal to something, maybe "0"? You wouldn't be able to solve this without that.

Answer:
x=9, y=10. (9, 10). The two numbers are 9 and 10.
Step-by-step explanation:
3x+5y=77
x+y=19
------------------
3x+5y=77
-3(x+y)=-3(19)
---------------------
3x+5y=77
-3x-3y=-57
-------------------
2y=20
y=20/2
y=10
x+10=19
x=19-10
x=9
