Question

1(234 + х)-4563 178; 2(х + 13,216) - 24,83- 5,17%;

Answer 1

Ответ:

Пошаговое объяснение:

1)(234 + х) - 456 = 178;

234 + х - 456 = 178;

х = 178 + 456 - 234;

х = 400;

2)(х+13,216)-24,83=5,17

х+13,216=5.17+24.83

х+13,216=30

х=30-13.216

х=16,784%

Answer 2

It seems like you've provided two mathematical expressions. However, the second expression appears to be a bit unclear due to the formatting. It seems like you want me to solve these expressions for the variable "x." Let's break down the expressions and solve for "x":

1. $1 \cdot (234 + x) - 4563 = 178$
2. $2 \cdot (x + 13.216) - 24.83 - 0.0517 \cdot x$

For the first expression:

$1 \cdot (234 + x) - 4563 = 178$

Distribute the 1: $234 + x - 4563 = 178$

Combine like terms: $x - 4329 = 178$

Add 4329 to both sides: $x = 4507$

So, for the first expression, $x = 4507$.

For the second expression:

$2 \cdot (x + 13.216) - 24.83 - 0.0517 \cdot x$

Distribute the 2: $2x + 26.432 - 24.83 - 0.0517 \cdot x$

Combine like terms: $1.9483 \cdot x + 1.602$

Subtract 1.602 from both sides: $1.9483 \cdot x = -1.602$

Divide by 1.9483: $x = -0.823$

So, for the second expression, $x \approx -0.823$.

Please double-check the formatting of the second expression if there were any errors in my interpretation.
