Solve for x and y simultaneously x-2y=3. 3x²-5xy-16y=24

Answers

Value of x = 0 or 1 and value of y = $(-3)/(2)$ or -1 for the given quadratic equation.

What is quadratic equation?

" Quadratic equation is defined as the polynomial whose highest degree of the given variable is equals to 2."

According to the question,

Given equations,

$x-2y=3$

⇒ $x=3 + 2y$ ____(1)

Quadratic equation,

$3x^(2) -5xy-16y=24$ ____(2)

Substitute the value of 'x' from (1) in (2) quadratic equation we get,

$3(3+2y)^(2) -5(3+2y)y-16y=24$

⇒ $3(9+12y+4y^(2) )-5y(3+2y) -16y-24=0$

⇒ $27+36y+12y^(2) -15y-10y^(2) -16y-24=0$

⇒ $2y^(2) +5y+3=0$

⇒ $2y^(2) +2y+3y+3=0$

⇒ $2y(y+1)+3(y+1)=0$

⇒ $(2y+3)(y+1)=0$

⇒ $(2y+3)=0 or (y+1)=0$

⇒ $y=(-3)/(2) or y = -1$

Substitute in (1) to get the value of 'x' ,

$x= 3+ 2((-3)/(2)) or x = 3 + 2 (-1)$

⇒ $x = 0 or x = 1$

Hence, value of x = 0 or 1 and value of y = $(-3)/(2)$ or -1 for the given quadratic equation.

x-2y=3 ⇒y=(x-3)/2
3x²-5xy-16y=24

We can suggest this system of equations by substitution method.
y=(x-3)/2

3x²-5x(x-3)/2-16(x-3)/2=24
least common multiple=2
6x²-5x(x-3)-16(x-3)=48
6x²-5x²+15x-16x+48=48
x²-x=0
x(x-1)=0
Now, we solve two equations:
1)x=0 ⇒y=(0-3)/2=-3/2
2)x-1=0
x=1 ⇒y=(1-3)/2=-1

Answer: we can two solutions:
solution1: x=0; y=-3/2
solution2: x=1, y=-1

Answers

Hey there!

Rotation is the term for a turn of a figure around a fixed point. During a rotation, a figure rotates around a center point by a specified angle.

Thanks!

The answer is C) rotation. If you look at the root of the word "rotation", then you will see the word rotate, which means to turn.

What is b - 3/16 = 5/16

Answers

If you would like to solve b - 3/16 = 5/16, you can do this using the following steps:

b - 3/16 = 5/16
b = 5/16 + 3/16
b = 8/16
b = 1/2

The correct result would be 1/2.

The solution to the equation b - 3/16 = 5/16 is b = 1/2.

To solve the equation b - 3/16 = 5/16, you need to isolate the variable b.

To eliminate the fraction, you can add 3/16 to both sides of the equation:

b - 3/16 + 3/16 = 5/16 + 3/16

Simplifying the equation:

b = 8/16

Now, you can simplify the right side of the equation:

b = 1/2

Therefore, the solution to the equation b - 3/16 = 5/16 is b = 1/2.
