Question

5(2x-7)-3(3x-8)=9x-16-2(3x-5)+13Urgentttttt!​

Answer 1

5 ( 2x - 7 ) - 3 ( 3x - 8 ) = 9x - 16 - 2 ( 3x - 5 ) + 13

10x - 35 - 9x + 24 = 9x - 16 - 6x + 10 + 13

10x - 9x - 9x + 6x = 13 + 10 - 16 - 24 + 35

-2x = 18

x = 18 / -2 ⇒ x = -9

Answer 2

Răspuns:  x = - 9

Explicație pas cu pas:

5(2 x - 7 ) - 3( 3 x - 8 ) = 9 x - 16 - 2( 3 x - 5 ) + 13

10 x - 35 - 9 x + 24 = 9 x - 16 - 6 x + 10 + 13

x - 11 = 3 x + 7

x - 3 x = 7 + 11

- 2 x = 18

x = 18 : ( - 2 )

x = - 9
