Question

22,9 × у - 0,49+ 2,1 × у = 12,01

Answer 1

22,9*у-0,49+2,1*у=12,01
22,9*у+2,1*у= 12,01+0,49
25у=12,5
у=12,5/25 
у=0,5 

Answer 2

22,9*y-0,49+2,1*y=12,01
22,9y-0,49+2,1y=12,01
25y=12,01+0,49
25y=12,5
y=12,5:25
y=0,5

Answer 3

To solve the equation for the variable "у," follow these steps:

Given equation: 22.9 * у - 0.49 + 2.1 * у = 12.01

Combine the like terms involving "у": (22.9 + 2.1) * у - 0.49 = 12.01 25 * у - 0.49 = 12.01

Add 0.49 to both sides of the equation: 25 * у = 12.01 + 0.49 25 * у = 12.5

Now, divide both sides by 25 to solve for "у": у = 12.5 / 25 у = 0.5

So, the solution for the equation is у = 0.5.
