Question

1) 491 863+ x= 800 5422) x:400=320​

Answer 1

Ответ:

1) 491863 + x = 800542

х = 800542 - 491863

х= 308679

_________________

491863 + 308679 = 800542

2) x : 400 = 320

х = 320 • 400

х = 128 000

____________

128 000 : 400 = 320

Answer 2

491863+x=800542
x=800542-491863
x=308679
Ответ: 308679
х:400=320
х=400*320
х=128000
Ответ: 128000

Answer 3

It looks like you have provided two mathematical equations. Let's solve them step by step:

Equation 1: $491,863 + x = 800,542$ To solve for $x$, you need to isolate $x$ on one side of the equation. Start by subtracting $491,863$ from both sides: $x = 800,542 - 491,863$ $x = 308,679$

So, in the first equation, $x = 308,679$.

Equation 2: $x / 400 = 320$ To solve for $x$, you need to isolate $x$ on one side of the equation. Multiply both sides by 400: $x = 320 \times 400$ $x = 128,000$

In the second equation, $x = 128,000$.

Therefore, the solutions for the two equations are:

1. $x = 308,679$
2. $x = 128,000$
