You can put this solution on YOUR website!
peanuts = x (lbs)
almonds = y (lbs)
x+y = 53
3x + 4y = 155
Using substitution
x = 53 - y
3(53-y) + 4y = 155
159 -3y + 4y = 155
y = 155 - 159 = -4???
57 lbs of peanuts and -4 lbs of almonds??
question is flawed

PEANUTS COST $3 PER POUND AND ALMONDS COST $4 PER POUND. CREATE A MIXTURE THAT IS 53 POUNDS OF NUTS AT A COST OF $155.
----------
$155/53 = $2.92/pound
Not possible. Any mix will be between $3 and $4 /pound.
