Y = 3x y = 1/2x Find by using systems of equation by elimination.

A. One solution
B. No Solution
C. Infinitely Many Solutions

Step-by-step explanation:

y = 3x + 0

y = 1/2x + 0

y = 3x + 0

-3x  -3x

y - 3x = 0

y = 1/2x + 0

2(y = 1/2x + 0)

2y = x + 0

-x     -x

2y - x = 0

y - 3x = 0

2y - x = 0

1(y - 3x = 0)    = y = - 3x = 0

-3(2y - x = 0)  = -6y + 3x = 0

y = - 3x = 0

-6y + 3x = 0

-5y = 0

/-5     /-5

y = 0

y = 3x + 0

0 = 3x + 0

-3x   -3x

-3x + 0 = 0

      - 0   -0

-3x = 0

/-3   /-3

x = 0

(x,y) -> (0, 0)

Hope this helps!

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
