a store is having a sale on walnuts and chocolate chips. for 3 pounds of walnuts and 5 pounds of chocolate chips, the total cost
Step2247 [10]

Answer:

  • Walnuts - $1.25, chocolate chips - $3.25

Step-by-step explanation:

Let walnuts = x, chocolate chips = y

<u>Set a system and solve:</u>

  • 3x + 5y = 20
  • 6x + 2y = 14

<u>Double the first equation and subtract the second one from it:</u>

  • 6x + 10y - 6x - 2y = 40 - 14
  • 8y = 26
  • y = 26/8
  • y = 3.25

<u>Find the value of x:</u>

  • 6x + 3.25*2 = 14
  • 6x = 14 - 6.5
  • 6x = 7.5
  • x = 7.5/6
  • x = 1.25

hammer [34]

Answer:

Y = - 24

Step-by-step explanation:

Y/-6 +5=9 /*6 (Multiply the whole equation by the number 6 to eliminate the fraction. That is, you multiply each member of the equation by 6 because 6 is in the denominator of the fraction.
\frac{Y}{-6} *6=-Y,     5*6=30,    9*6=54

-Y + 30 = 54
-Y = 54-30
-Y=24 /*(-1)
Y= -24
