Question

19,5 - (x + 3,7) = 12,7

Answer 1

Ответ: x=3.1

19-(х+3.7)-19.5=12.7-19.5

-(х+3.7)=-6.8

x+3.7=6.8

x+3.7-3.7=6.8-3.7

x=3.1

Answer 2

Відповідь:

19,5-(х+3,7)=12,7

19,5-х-3,7=12,7

-х=12,7-19,5+3,7

-х=-6,8+3,7

-х=-3,1|:(-1)

х=3,1

Відповідь: х=3,1.

Answer 3

To solve the equation $19.5 - (x + 3.7) = 12.7$, you can start by simplifying the equation step by step.

First, distribute the negative sign inside the parentheses:

$19.5 - x - 3.7 = 12.7$

Next, combine the constant terms on the left side:

$15.8 - x = 12.7$

To isolate $x$, subtract 15.8 from both sides of the equation:

$-x = 12.7 - 15.8$

$-x = -3.1$

Finally, multiply both sides by -1 to solve for $x$:

$x = 3.1$

So, the solution to the equation $19.5 - (x + 3.7) = 12.7$ is $x = 3.1$.
