Given y=x+4 and y=x^2 +4x, find x and y.

y=x+4 ...............(1)

...........(2)

plugging value of y from (1) in (2)

from here we get two values of x as

x-1=0, x=1 and x+4=0, x=-4

plugging x=1 in equation (1)

y=x+4 =1+4=5

plugging x=-4 in equation (1) , we get

y=x+4 =4-4 =0

so for x=1, y=5 and x=-4, y=0

x=1, y=5 and x=-4, y=5 points are (1,5) and (-4,5)

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
