Question

0,4(6-4у)=0,5(7-3у)-1,94

Answer 1

Ответ:

y = 8,4

y = 42/5 , y = 8 2/5

Answer 2

2,4-1,6у=3,5-1,5у-1,94
-1,6у+1,5у=3,5-1,94-2,4
-0,1у=-0,84
у=8,4

Answer 3

To solve the equation 0.4(6-4y) = 0.5(7-3y) - 1.94, we will perform the following steps:

1. Distribute the multiplication on both sides of the equation: 2.4 - 1.6y = 3.5 - 1.5y - 1.94

2. Combine like terms on both sides: -1.6y + 1.5y = 3.5 - 1.94 - 2.4

   -0.1y = -0.84

3. Divide both sides by -0.1 to isolate y: y = (-0.84) / (-0.1)

   y = 8.4

Therefore, the solution to the equation is y = 8.4.
