Step-by-step explanation:

19 cosθ=5 cosθ+14

19cosθ-5 cosθ=14

14 cos θ=14

cos θ=1=cos (0)=cos (0+2k π)

θ=0+2kπ,where k is an integer.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
