Answer: x =-7 and y =10

Step-by-step explanation:

The given system of equations :

4x-y=-38..................(1)\\x+y=3...........................(2)

Add equation (1) and (2), we get

4x+x-y+y=-38+3\\\\\Rightarrow5x=-35\\\\\Rightarrow\ x=\frac{-35}{5}=-7\\\\\Rightarrow\ x=-7

Put value of x in (2), we get

-7+y=3\\\\\Rightarrow\ y=3+7=10

hence, the solution of the given system is  x =-7 and y =10.

When simplifying 4x^3-10x^2+6x/2x^3+x^2-3x, what are the term(s) that can be cancelled
brilliants [131]

Answer:

x can be cancelled

Step-by-step explanation:

we are given

\frac{4x^3-10x^2+6x}{2x^3+x^2-3x}

Firstly, we will factor numerator and denominator

and then we can factor it

4x^3-10x^2+6x=2x(2x^2-5x+3)

4x^3-10x^2+6x=2x(2x+1)(x-3)

now, we can factor denominator

2x^3+x^2-3x=x(2x^2+x-3)

2x^3+x^2-3x=x(x-1)(2x+3)

now, we can replace it

\frac{4x^3-10x^2+6x}{2x^3+x^2-3x}=\frac{2x(2x+1)(x-3)}{x(x-1)(2x+3)}

we can see that

both terms are having x common

so, x can be cancelled

So,

x can be cancelled
