Question

Given the simultaneous equations,

x= -2y+15
x=y²
the solutions are :

Answer 1

OMG you are asking so many questions so quickly

After a bit of substitution we can get y² + 2y - 15 = 0

I think you can solve this equation without any worries (✿◠‿◠)

Answer 2

Answer:

y^2+2y-15=0

y^2+5y-3y-15=0

y(y+5)-3(y+5)=0

(y-3)(y+5)=0

(3,-5)

hope it helps.
