Question

(8x +10) (3 -x) = (11-2x)(4x+5)-5​

Answer 1

Ответ:

$(8x + 10)(3 - x) = (11 - 2x)(4x + 5) - 5 \\ 24x - 8 {x}^{2} + 30 - 10x = 44x + 55 - 8 {x}^{2} - 10 - 5 \\ 14x - 8 {x}^{2} + 30 + 8{x}^{2} = 44x + 40 \\ - 30x = 10 \\ x = - \frac{1}{3}$

Answer 2

Ответ:

24x-8x²+30-10x=44x+55-8x²-10x-5

-8x²+8x²+24x-10x-44x+10x=55-5-30

-20x=20

x= 20:(-20)

x= -1
