<h2>
Therefore x=2 and y= 1</h2>
Step-by-step explanation:
Given equations are
and 
.........(2)
⇒
.......(1)
Equation (2)× 3 - Equation (1)
⇔
⇔-10y = -10
⇔y=1
Putting the value of y in equation (1) we get
⇔x =2
Therefore x=2 and y= 1
Does this mean how to write it? If so, then it is written:
X= the number
(See picture)
Answer:
X=1.132589
Step-by-step explanation:
If im correct the answer would be x=1.132589
3
x2−1
−2(x+3)=
5
x+1
3
(x+1)(x−1)
+−2x−6=
5
x+1
Multiply all terms by (x+1)(x-1) and cancel:
3+(−2x−6)(x+1)(x−1)=5(x−1)
−2x3−6x2+2x+9=5x−5(Simplify both sides of the equation)
−2x3−6x2+2x+9−(5x−5)=5x−5−(5x−5)(Subtract 5x-5 from both sides)
−2x3−6x2−3x+14=0
(Use cubic formula)
x=1.132589
