Answer:

x = 17 because 8x + 20 equals 11x-31, you simplify both by subtrcting 8x from both sides to get 20 = 3x -31. Then you add 31 to both sides to get 51 = 3x. Then divide 3 from both sides and you get 17 = x

Solve the equation X/-2=5

Ipatiy [6.2K]

Answer:

$\boxed {x = -10}$

Step-by-step explanation:

Solve for the value of $x$ :

$\frac{x}{-2} = 5$

-Multiply both sides by $-2$

$x = 5 \times (-2)$

$\boxed {x = -10}$

So, therefore, value of $x$ is $-10$ .

What is the solution to this equation?

pychu [463]

Answer:

A. x = 3

Step-by-step explanation:

5x+15 + 2x = 24 +4x

7x+15=24+4x

7x+15-15=24+4x-15

7x=4x+9

7x-4x=4x+9-4x

3x=9

Step-by-step explanation:

these angles are supplementary angles, meaning that when added together, they equal 180°

so you just need to subtract 41 from 180 which gets you 139.

<h3>Answer:</h3>

A. $6x^2$ +-5x+14x+-35

$6x^2$ +9x-35

B. $5x^4+-3x^3+10x^3+-6x^2$

$5x^4+7x^3-6x^2$

C. $25x^2+-20x+20x+-16$

$25x^2-16$

D. $x^4+-4x^2+-7x^2+28$

$x^4-11x^2+28$

$====================================$

Step-by-step explanation:

A. (3x*2x)+(3x*-5)+(7*2x)+(7*-5)

Multiply and simplify.

$6x^2$ +9x-35

B. ( $x^2*5x^2$ )+( $x^2*$ -3x)+(2x $*5x^2$ )+(2x $*-3x$ )

Multiply and simplify.

$5x^4+7x^3-6x^2$

C. $(5x*5x)+(5x*-4)+(4*5x)+(4*-4)$

Multiply and simplify.

$25x^2-16$

D. $(x^2*x^2)+(x^2*-4)+(-7*x^2)+(-7*-4)$

Multiply and simplify.

$x^4-11x^2+28$

I hope this helps!

But you should really do this yourself.
