Question

это дробь. 8Х-53 - 4Х+34 + 2-9Х2 = -3

Answer 1

(8х-5)/3  - (4х+3)/4  + (2-9х)/2 = -3             |*12
4(8x-5) - 3(4x+3) + 6(2-9x) = -3 *12
32x -20 - (12x+9) +12-54x=-36
32x -20 -12x-9 +12-54x=-36
-34x -17=-36
-34x= -36+17
-34x= -19
x= (-19) /(-34)
x= 19/34

Answer 2

$frac{8x-5}{3}-frac{4x+3}{4}+frac{2-9x}{2}=-3\frac{8x-5}{3}-frac{4x+3}{4}=-frac{6}{2}-frac{2-9x}{2}=-frac{6}{2}+frac{9x-2}{2}=frac{9x-2-6}{2}\frac{8x-5}{3}=frac{2(9x-8)}{4}+frac{4x+3}{4}=frac{18x-16+4x+3}{4}\frac{8x-5}{3}=frac{22x-13}{4}to\(8x-5)4=3(22x-13)\32x-20=66x-39\32x-66x=-39+20\-34x=-19to x=frac{19}{34}$
