Answer:

Let's solve your equation step-by-step.

4−4x=12+20x

Step 1: Simplify both sides of the equation.

4−4x=12+20x

4+−4x=12+20x

−4x+4=20x+12

Step 2: Subtract 20x from both sides.

−4x+4−20x=20x+12−20x

−24x+4=12

Step 3: Subtract 4 from both sides.

−24x+4−4=12−4

−24x=8

Step 4: Divide both sides by -24.

= -24x/-24 = 8/-24

answer:

X= -1/3

Solving systems by Substitution Homework y=x+4 y=x-3

zvonat [6]

There is no solution for this equation since they have the same slope, x/1. The only difference between these two is that their y intercepts are different meaning that they will be parallel lines that will never intersect among one other. For example, think of it as two separate lines that are have the same slope and never gain more distance/units from one another.

Solve:

To solve, you have to get one of this equations into a Ax+By=C equation form, standard equation. Let’s change y=x+4 into a standard equation.

We have to get x and y together and 4 as C.
So let’s subtract x from both sides;

y=x+4
-x -x
————————
-x+y=4

This is a standard equation.

Now let’s substitute.

take the standard equation and plug in y which is x+4 since there is a equation meaning it’s y=x+4

-x+(x+4)=4

Let’s simplify this mess.

-x+x equals 0. So we are left with 4=4.

Subtract 4 from both sides and we get 0=0

This means there is no solution. Hoped this helped.

Add the following polynomial of x3+3xy-2×y2+y3,2×3-5x2y-3xy2-2y3

ANTONII [103]

The addition of the polynomial $x^{3}+3xy-2xy^{2} +y^{3}$ with $2x^{3}-5x^{2} y-3xy^{2}-2y^{3}$ is $3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}$ .

What is a polynomial?

⇒ A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

⇒ In the addition of polynomials, the like terms are added while in subtraction, the like terms are subtracted.

Calculation;

We have been given two polynomial which we have to add $x^{3}+3xy-2xy^{2} +y^{3}$ and $2x^{3}-5x^{2} y-3xy^{2}-2y^{3}$

The sign after addition or subtraction will always be of the variable having more value.

$(x^{3}+3xy-2xy^{2} +y^{3} )+(2x^{3}-5x^{2} y-3xy^{2}-2y^{3})$
