Question

(2,3y-11,2)*(-2,1)=(1,7y-9,4)*0,7

Answer 1

( 2,3у - 11,2 ) * ( - 2,1 ) = ( 1,7у - 9,4 ) * 0,7

- 4,83у + 23,52 = 1,19у - 6,58

- 4,83у - 1,19у = - 6,58 - 23,52

- 6,02у = - 30,1

у = - 30,1 / ( - 6,02 )

у = 5

Ответ : 5

Answer 2

$(2.3y - 11.2) \times ( - 2.1) = (1.7y - 9.4) \times 0.7 \\ - 4.83y + 23.52 = 1.19y - 6.58 \\ - 4.38y - 1.19y = - 6.58 - 23.52 \\ - 6.02y = - 30.1 \\ y = - 30.1 \div ( - 6.02) \\ y = 5$Ответ: у=5
