10x+2y=20
2x+3y=-21
can u me find the solution
,19),-5)3.(1,6)4.no solution

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

jbankston is right, use thhe link and you should find the answer.
