Equation R: -3y = -3x - 9
Equation S: y = x + 3
Replace y in Equation R with equation S:
-3(x+3) = -3x - 9
Use distributive property:
-3x -9 = -3x -9
Because both sides of the equation are identical x can be any number and they would still be equal.
This means there are Infinite solutions.
Answer:
Given x = 2 and y =4
so 16
+2![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
![y^{-1}](https://tex.z-dn.net/?f=y%5E%7B-1%7D)
= 16*
+ 2*
*![4^{-1}](https://tex.z-dn.net/?f=4%5E%7B-1%7D)
= 16 + (2*4)/4
=16 + 8/2
16 + 2
=18
Step-by-step explanation:
According to the given cubic equation 8x³-10x² - 21x + 18 = 0 the other value of x will be 4.
<h3>How does one solve a three-degree equation?</h3>
Traditionally, a cubic problem can be solved by converting it to a quadratic equation and then solving it using factoring or the quadratic formula. A cubic equation, like a quadratic equation, has three roots.
<h3>What is the simplest method for solving a cubic equation?</h3>
The typical strategy for solving a cubic problem is to convert it to a quadratic equation and then solve the quadratic using the standard methods, either factoring or using the formula. All of them are cubic equations. A cubic equation, like a quadratic equation, may have two or three real roots.
<h3>According to the given data:</h3>
8x³-10x² - 21x + 18 = 0
x= 2
substituting the value in the equation we get:
8x³-10x² - 21x + 18 = 0
8(2)³-10(2)² - 21(2) + 18 = 0
68 - 40 - 42 + 18 = 0
4 = 0
According to the given equation 8x³-10x² - 21x + 18 = 0 the other value of x will be 4.

Answer:
(x) = ![\frac{4x-48}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4x-48%7D%7B3%7D)
Step-by-step explanation:
let y = h(x) and rearrange making x the subject, that is
y =
x + 12 ( multiply through by 4 to clear the fraction )
4y = 3x + 48 ( subtract 48 from both sides )
4y - 48 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) = ![\frac{4x-48}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4x-48%7D%7B3%7D)
