Answer 2

Answer:

3x + 2/2x + 3 = 6x + 7/ 4x+ 5

by cross multiplication method

(3x+2)(4x+5) = (2x+3)(6x+7)

(3x+2)(4x+5) = (2x+3)(6x+7)12x²+15x+8x+10=12x²+14x+18x+21

(3x+2)(4x+5) = (2x+3)(6x+7)12x²+15x+8x+10=12x²+14x+18x+2112x²-12x²+23x+10=32x+21

(3x+2)(4x+5) = (2x+3)(6x+7)12x²+15x+8x+10=12x²+14x+18x+2112x²-12x²+23x+10=32x+2123x+10=32x+21

(3x+2)(4x+5) = (2x+3)(6x+7)12x²+15x+8x+10=12x²+14x+18x+2112x²-12x²+23x+10=32x+2123x+10=32x+2123x-32x=21-10

(3x+2)(4x+5) = (2x+3)(6x+7)12x²+15x+8x+10=12x²+14x+18x+2112x²-12x²+23x+10=32x+2123x+10=32x+2123x-32x=21-10-9x=11

(3x+2)(4x+5) = (2x+3)(6x+7)12x²+15x+8x+10=12x²+14x+18x+2112x²-12x²+23x+10=32x+2123x+10=32x+2123x-32x=21-10-9x=11x=11/-9

Hence the value of x will be 11/-9
