Question

389+( х-47) =819 ( х+631)-567=666

Answer 1

$389+(x-47)=819$
$x-47=819-389$
$x-47=430$
$x=430+47$
$x=477$
Ответ $: 477.$
$(x+631)-567=666$
$x+631=666+567$
$x+631=1233$
$x=1233-631$
$x=602$
Ответ $: 602.$

Answer 2

389+(х-47)=819
(х-47)=819-389
(х-47)=430
х=430+47
х=477

(х+631)-567=666
(х+631)=666-567
(х+631)=99
х=631-99
х=532

Answer 3

Let's break down the given equation step by step and solve for the unknown variable 'x':

1. 389 + (x - 47) = 819(x + 631) - 567
2. Simplify the left-hand side by combining like terms: 342 + x = 819x + 516789 - 567
3. Simplify the right-hand side by combining like terms: 342 + x = 819x + 516222
4. Subtract x from both sides of the equation: 342 = 818x + 516222
5. Subtract 516222 from both sides of the equation: -515880 = 818x
6. Divide both sides by 818: x = -630.43 (rounded to two decimal places)

Therefore, the solution to the equation is x = -630.43.
