Question

(x+450)-3540 = 4000:80 (1234+n)+2140 = 52741 4 класс

Answer 1

Ответ:

(x+450)-3540 = 4000:80  

x+450-3540 = 50  

x-3090 = 50  

x = 50+3090  

x = 3140

(1234+n)+2140 = 52741  

1234+n+2140 = 52741  

n+3374 = 52741  

n = 52741-3374  

n = 49367

Answer 2

It looks like you've provided two algebraic expressions. Let's solve them step by step.

1. $(x + 450) - 3540 = 4000 \times 80$

First, simplify the left side of the equation:

$x + 450 - 3540 = 4000 \times 80$

Combine like terms:

$x - 3090 = 4000 \times 80$

Now, isolate $x$ by adding 3090 to both sides:

$x = 4000 \times 80 + 3090$

Calculate the right side:

$x = 320000 + 3090$

$x = 323090$

So, the solution to the first equation is $x = 323090$.

2. $(1234 + n) + 2140 = 52741$

Combine like terms on the left side:

$1234 + n + 2140 = 52741$

Combine the constants:

$n + 3374 = 52741$

Isolate $n$ by subtracting 3374 from both sides:

$n = 52741 - 3374$

$n = 49367$

So, the solution to the second equation is $n = 49367$.
