5x – 2x + 7 – x = ?x + ?

fomenos

Step-by-step explanation:

5x – 2x + 7 – x = ?x + ?

I need the answer for "no solution" and "infinite solutions".

NO SOLUTION:

no solution because any value you give to x is not solvable, it remains +7

5x – 2x + 7 – x = ?x + ?

2x = 2x + 7

INFINITE SOLUTION

infinite solutions because any value you give to x is solvable

5x – 2x + 7 – x = ?x + ?

5x – 2x + 7 – x = 2x + 7

2x + 7 = 2x + 7

Factor completely B. (x+5)²-2(x+5)-24 C. (x+2)²-8(x+2)+15 D. 2(2x-1)²-9(2x-1)+4

Sladkaya [172]

B.
${x}^{2} + 10x + 25 - 2x - 10 - 24 = \\ x {}^{2} + 8x - 9 = \\ (x - 1)(x + 9)$

C.
${x}^{2} + 4x +4 - 8x - 16 + 15 = \\ x {}^{2} - 4x + 3 = \\ (x - 3)(x - 1)$
D.
$2( {4x}^{2} - 4x + 1) - 18x + 9 + 4 = \\ 8x {}^{2} - 8x + 2 - 18x + 13 = \\ 8x {}^{2} - 26x + 15$

please mark as brainliest.
