Question

A} 3,8*{x=1,3}=0,5 б} 9,3y-5,7y=16,2

Answer 1

) 3,8*(х+1,3) = 9,5

3,8х+ 4,94 = 9,5

3,8х= 9,5-4,94

3,8х=4,56

х=1,2

2) 9,3у-5,7у=16,2

3,6у=16,2

у=16,2/3,6

у=4,5

есть только такое,может что то попутали??

Answer 2

It looks like you have two equations, and you'd like to solve for the variables x and y in each equation. Let's solve them one by one:

a) 3.8 * (x + 1.3) = 0.5

First, let's distribute the 3.8 on the left side:

3.8x + 3.8 * 1.3 = 0.5

Now, subtract 3.8 * 1.3 from both sides:

3.8x = 0.5 - 3.8 * 1.3 3.8x = 0.5 - 4.94

Next, subtract 4.94 from both sides:

3.8x = -4.44

Now, divide both sides by 3.8 to isolate x:

x = -4.44 / 3.8 x ≈ -1.17

So, the solution for equation (a) is x ≈ -1.17.

b) 9.3y - 5.7y = 16.2

Combine like terms on the left side:

(9.3 - 5.7)y = 16.2

Now, calculate the difference between 9.3 and 5.7:

3.6y = 16.2

Next, divide both sides by 3.6 to isolate y:

y = 16.2 / 3.6 y = 4.5

So, the solution for equation (b) is y = 4.5.

To summarize: a) x ≈ -1.17 b) y = 4.5
