Find the solution of this system of equations? -8x-6y=60 5x+6y=-69

First subtract the x variable on both sides so on the first equation youll have -6y=8x+60 then divide 6 on all variables which means youll have y=8/6x+10 and in the second equation you do the same thing and youll have y=-5/6x-11.5

Divide -8x by -8 which leaves you with x and you have to do it to both sides so divide 60 by -8 which leaves you with -7.5
and continue doing all algebraic equations that way following the two rules:
1) to get rid of a number do its opposite
2)whatever you do to one side do to the other

Find the least common denominator x^4/x^2+2x+1 and -8/x^2+5x+4

Harman [31]

Answer:

(x + 4)(x + 1)(x + 1) or (x + 4)(x + 1)²

Step-by-step explanation:

Factor both denominators and see what you are missing between them

(x^4)/[(x + 1)(x + 1) -8/[x + 4)(x + 1)]

So in order to get a common denominator, we need

(x + 4)(x + 1)(x + 1) as a denominator, or (x +4)(x + 1)²
