Answer:

2(3x+4) = 11x-17

6x+8 = 11x-17

25=-5x

x=-5

11x-17

55-17

AC = 38

CD = 38

49-38 = 11

DE = 11

Let me know if this helps!

64 +16x +x² = x² +225

16x = 161

x = 161/16 = 10 1/16 = 10.0625 . . . cm

What is the answer of the problem; <br> 3x-4+2(x-5)=9x+8-2x

alexgriva [62]

Answer:

The answer to the given problem $3x-4+2(x-5)=9x+8-2x$ is x=-11

Step-by-step explanation:

Given problem is $3x-4+2(x-5)=9x+8-2x$

To solve the equation:

$3x-4+2(x-5)=9x+8-2x$

$3x-4+2x-10=9x+8-2x$ (multiplying the term with factor)

$5x-4-10=7x+8$ (adding the like terms)

$5x-14=7x+8$ (adding the like terms)

Now taking the terms to one side

$5x-14-7x-8=0$

$-2x-22=0$ (adding the like terms)

$-2x=22$

$-x=\frac{22}{2}$

$-x=11$

x=-11

Therefore x=-11

The answer to the given problem $3x-4+2(x-5)=9x+8-2x$ is x=-11
