Solve the following systems of equations

Varvara68 [4.7K]

Answer:

$(-1;1)$ and $(0;4)$

Step-by-step explanation:

First of all, even if the system is of 4th degree, by looking at the shape of the equations I am expecting up to 2 solutions.

The easiest way to solve it, since both equation are in the form y= something, is to equate both RHSs.

$3x^2+6x+4=-3x^2+4\\6x^2+6x=0 \rightarrow 6x(x+1)=0$

which tells us that either $x=0$ or $x=-1$

Now we can replace these value of x in one of the two to finish our work: $x=0\rightarrow y= 4$

$x=-1 \rightarrow y= -3+4=1$

Solve the equation for x: 2x + 22 = 4(x+3)

Elina [12.6K]

2x + 22 = 4(x + 3)...distribute thru the parenthesis
2x + 22 = 4x + 12...subtract 2x from both sides, subtract 12 from both sides
22 - 12 = 4x - 2x...simplify
10 = 2x...divide both sides by 2
10/2 = x...reduce
5 = x <==
