HELP! I don’t know what to do for #4. well i don’t know what to put for another equation. i Dont need help solving i just need help doing another equation

Answer 1

Let s = #small notebooks

Let L = #large notebooks

 

We Can set up two equations from the info given.

 

s + L = 6           bought 6 notebooks total

8s + 10L = 56    spent $56

 

Solve equation 1 for one variable.

L = 6-s

 

Plug 6-s in equation 2 in place of L

and solve for s

 

8s + 10(6-s) = 56

8s + 60 - 10s = 56

-2s + 60 = 56

-2s = -4

s = (-4)/(-2)

s = 2

 We know s+L = 6 and s=2

2+L = 6

L = 4

 4 large notebooks and 2 small notebooks

were purchased
