1.) What is the solution to the system of equations below? y = 2x + 8 3(-2x + y) = 19

-BARSIC- [3]

Answer:

y = 2x + 8

6x + 3y = 19

6x + 3(2x + 8) = 19

6x + 6x + 24 = 19

12x = -5

x = -5/12

y = 2(-5/12) + 8

y = -5/6 + 48/6

y = 43/6

Multiply by 12
And you get (1/2)*12 which is 6=x lemons

He needs 6 cups of lemons
