Question

А) x+3,12=5,43 б)1 3 - y= 2 7 14 10​

Answer 1

Пошаговое объяснение:

$x +3.12 = 5.43 \\ x = 2.31$

$13 - y = 27 \\ - y = 27 - 13 \\ - y = 14 \\ y = - 14$

$14 - 10 = 4$

Answer 2

Відповідь:

Покрокове пояснення: 1. х=5,43-3,12

х=2,31

2.13-у=27

-у=27-13

-у=14 это мы можем поделить на -1 чтобы у стал с +

И тогда

у=-14

14-10=4

Answer 3

It looks like you have provided two equations, and it seems you want to solve for the variables in each equation. Let's solve them step by step:

a) Equation 1: x + 3.12 = 5.43

To solve for x, you can isolate x on one side of the equation: Subtract 3.12 from both sides of the equation: x = 5.43 - 3.12 x = 2.31

So, the solution for equation (a) is x = 2.31.

b) Equation 2: 13 - y = 27 + 14 * 10

Let's solve for y: First, perform the multiplication on the right side of the equation: 27 + 14 * 10 = 27 + 140 = 167

Now, subtract 167 from both sides of the equation: 13 - y = -167

To solve for y, you can isolate y on one side of the equation by multiplying both sides by -1 (which changes the sign): y = 167 - 13 y = 154

So, the solution for equation (b) is y = 154.

In summary: a) x = 2.31 b) y = 154
