Question

sasha , julia and viko go shopping . sasha spends 8$ less than twice the amount that vika spent julia spends 12$ more then vika spent

Answer 1

Sasha spent = 2x-8      
Julia spent = x + 12
x = what vika spent
2x-8 = x+12
 -x          -x
x - 8 = 12
+8       +8
x = 20 

2(20) -8 = what sasha spent
40 - 8 = 32

20 +12 = what julia spent
32

Vika spent = $20
Sasha spent =$32
Julia spent= $32
