Question

What is the value of x in the given equation ? (3x – 8)(3x + 2) – (4x – 11)(2x + 1) = (x – 3)(x + 7)​

Answer 1

Answer:

the value of x is 4

Step-by-step explanation:

(3x-8) (3x+2) - (4x-11) (2x+1) =(x-3) (x+7)

3x(3x+2)-8(3x+2)-{4x(2x+1)-11(2x+1)} =x(x+7)-3(x-7)

9x² - 6x-24x-16-(8x² +4x-22x-11)=x² +7x-3x-21

9x²-18x-16-8x2 -4x+22x+11=x² +7x-3x-21

x²-22x +22x -5=x²+4x-21

x²-5=x²+4x-21

x²-x²=4x-21+5

-4x = -21 +5

-4x = -16

4x = 16

x= 16/4

x= 4

Answer 2

Answer:

X=4
