Question

0,2(2х+0,5)-0,3(2у-3)=1,8

Answer 1

0,2(2х + 0,5) - 0,3(2у - 3) = 1,8

0,4х + 0,1 - 0,6у + 0,9 = 1,8

0,4х + 1 - 0,6у = 1,8

0,4х = 1,8 - 1 + 0,6у

0,4х = 0,8 + 0,6у

х = 2 + 1,5у

Answer 2

Ответ:

...

Объяснение:

0,2(2х+0,5)-0,3(2у-3)=1,8

1/5(2х+1/2)-3/10(2у-3)=9/5

1+2х/5-3у/5=9/5

2х/5=1/5(3у+4)

х=1/2(3у+4)

Answer 3

To solve the equation 0.2(2x + 0.5) - 0.3(2y - 3) = 1.8, we'll follow these steps:

Step 1: Distribute the multiplication: 0.4x + 0.1 - 0.6y + 0.9 = 1.8

Step 2: Combine like terms: 0.4x - 0.6y + 1 = 1.8

Step 3: Move constant term to the other side: 0.4x - 0.6y = 1.8 - 1

Step 4: Simplify the right side: 0.4x - 0.6y = 0.8

Now, the equation is in simplified form. If you have any further requirements or if I can assist you with anything else, please let me know.
