i know i just need help setting the equation

Answer 3

Ok, call big one b
call small one s
b = 1 + 2 s
b + s = 3 b - 20

Answer 4

can u help me work it out please

Answer 5

from the first equation you know that you can use the quantity (1 + 2 s) for b
so do that
1 + 2 s + s = 3 (1 + 2 s) - 20
or
1 + 3 s = 3 + 6 s - 20
solve that for s, then go back and find b

Answer 6

b=13,s=6
