What is the solution set of this equation?
i will give brainliest and i will ask another question with more points if you answer this.

to find x and y , we have to use simultaneous equations

3x-0.5y=6

-2x-y=4

if you want to cancel y and find x, multiply the first equation by 2 and subtract the 2 equations

= 6x-y=12

--2x-y=4

= 8x=8

x=1

substitute

(3*1)-0.5y=6

3-0.5y=6

-0.5y=3

y=-6

check:  3-(0.5*-6)=6

          3--3=6

        3+3=6

       6=6

and -2+-(-6)=4

-2--6=4

-2+6=4

4=4

the image is given below

since the options are not given so we draw it from the equation

the given equation is

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

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
