3(x - 3) + 8x = 5(2x + 1)

Expanding the terms,

3(x - 3) + 8x = 5(2x + 1) \\ 3x - 9 + 8x = 10x + 5

Collecting like terms,

3x - 9 - 8x = 10x + 5 \\ 3x - 8x - 10x = 5 + 9

Evaluating the terms,

3x - 8x - 10x = 5 + 9 \\  - 15x = 14

Divide both sides by -15,

- 15x = 14 \\ x =   - \frac{14}{15}

PLS HELP ME ASAP FOR 1 and 2 (SHOW WORK!! + Brainliest!) LOTS OF POINTS!! (Kinda)
liubo4ka [24]
For number one, the answer will be C because the ratio between the side and the perimeter of the Pentagon will be 1/5 or 2/10 or 3/15. For number 2, we know that the Pentagon had 5 sides, and the side of it is 8, so the perimeter of this Pentagon will be 8+8+8+8+8 or 40 inches, which is C. Hope it help!

Solve 4/x-4=x/x-4-4/3 for x and determine if the solution is extraneous or not
4vir4ik [10]

<u>Answer:</u>

x = 4 (extraneous solution)

<u>Step-by-step explanation:</u>

\frac { 4 } { x - 4 } = \frac { x } { x - 4 } - \frac { 4 } { 3 } \\ \frac { 4 } { x - 4 } - \frac { x } { x - 4 } = - \frac { 4 } { 3 } \\ \frac { 4 - x } { x - 4 } = - \frac { 4 } { 3 } \\ 3 ( 4 - x ) = - 4 ( x - 4 ) \\ 1 2 - 3 x = - 4 x + 1 6 \\ 4 x - 3 x = 1 6 - 1 2 \\ x = 4 \\

This solution is extraneous. Reason being that even if it can be solved algebraically, it is still not a valid solution because if we substitute back x=4, we will get two fractions with zero denominator which would be undefined.
