Question

A) (4,3-y) + 11, 37 =13, 2 б) (3x-15,8).4=14,8​

Answer 1

1. (4.3 - y) + 11.37 = 13
Розв'язок:
12 - y + 11.37 = 13
-y + 11.37 + 12 = 13
-y + 23.37 = 13
-y = 13 - 23.37
-y = -10.37
y = 10.37

2. (3x - 15.8) * 4 = 14.8
Розв'язок:
3x - 15.8 = 14.8 / 4
3x - 15.8 = 3.7
3x = 3.7 + 15.8
3x = 19.5
x = 19.5 / 3
x = 6.5

Answer 2

Let's solve the given equations:

A) $(4,3-y) + 11, 37 = 13, 2$

Firstly, it seems there might be a formatting issue or misunderstanding in the equation. If you meant $(4,3 - y) + 11.37 = 13.2$, then you can proceed as follows:

$4.3 - y + 11.37 = 13.2$

Combine like terms:

$15.67 - y = 13.2$

Subtract 15.67 from both sides:

$-y = -2.47$

Multiply both sides by -1 to solve for y:

$y = 2.47$

So the solution to the equation is $y = 2.47$.

B) $(3x - 15.8) \cdot 4 = 14.8$

Distribute the 4 on the left side:

$12x - 63.2 = 14.8$

Add 63.2 to both sides:

$12x = 78$

Divide both sides by 12:

$x = \frac{78}{12}$

Simplify:

$x = 6.5$

So the solution to the equation is $x = 6.5$.
