Question

I have 3 questions for math

Answer 1

Answer:

1. no question content
2. (x, y) = (1/2, 4)
3. (x, y) = (2, 10)

Step-by-step explanation:

1. No link, no question

__

2. Divide the first equation by 2 and substitute for y using the expression in the second equation.

  2x +(4x+2) = 5

  6x = 3 . . . . . . . . . subtract 2

  x = 3/6 = 1/2 . . . . divide by2

  y = 4(1/2) +2 = 4 . . . . substitute into the equation for y

The solution is (x, y) = (1/2, 4).

3. The solution using a graphing calculator is (x, y) = (2, 10). (see attached)
