Question

3381-(х+1730)=1008 2433+(1659-х)=3509

Answer 1

Ответ:

1) x=643

3381-x-1730=1008

1651-1008=x

x=643

2) x=583

1659-x=3509-2433

x=583

Answer 2

To solve the equations, we'll isolate $x$ in each equation. Let's go step by step:

Equation 1:

$3381 - (x + 1730) = 1008$

First, distribute the negative sign:

$3381 - x - 1730 = 1008$

Next, combine like terms:

$1651 - x = 1008$

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

$-x + x = 1008 - 1651$

$0 = -643$

The equation $0 = -643$ is not true, which means the first equation has no solution.

Equation 2:

$2433 + (1659 - x) = 3509$

First, simplify the expression inside the parentheses:

$2433 + 1659 - x = 3509$

Combine like terms:

$4092 - x = 3509$

Now, isolate $x$ by subtracting 4092 from both sides:

$-x = -583$

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

$x = 583$

So, in the second equation, $x = 583$.
