Question

Hey if you could help me with this it'd mean a lot I can't figure it out

L+S=17
3L+2S=46
What is S and what is L?

Answer 1

L = 12 S = 5

Explanation:

L+S=17

3L+2S=46

Multiply the first equation by -2

-2L -2S = -34

Then add it to the second equation

-2L -2S = -34

3L+2S=46

------------------

L = 12

Now we can find S

L+S = 17

12 + S = 17

Subtract 12 from each side

S = 17-12

S = 5
