Question

X-234=659+124 983-59+y=406 x-218=677+23 (349+56)-y=12

Answer 1

983-59+у=406
у=406-983+59
у= - 518

х-218=677+23
х=677+23+218
х=918

(349+56)-у=12
349+56-12=у
у=393

Answer 2

Let's solve each of the equations step by step:

1. X - 234 = 659 + 124

To isolate X, we can add 234 to both sides of the equation:

X - 234 + 234 = 659 + 124 + 234

This simplifies to:

X = 659 + 124 + 234

Combining the numbers on the right side:

X = 983 + 234

X = 1217

Therefore, the solution to the first equation is X = 1217.

2. 983 - 59 + y = 406

To solve for y, we can start by subtracting 983 and adding 59 to both sides of the equation:

983 - 59 + y - 983 + 59 = 406 - 983 + 59

Simplifying:

y = 406 - 983 + 59

Combining the numbers on the right side:

y = -517 + 59

y = -458

So, the solution to the second equation is y = -458.

3. x - 218 = 677 + 23

To solve for x, we can add 218 to both sides of the equation:

x - 218 + 218 = 677 + 23 + 218

Simplifying:

x = 677 + 23 + 218

Combining the numbers on the right side:

x = 898

Therefore, the solution to the third equation is x = 898.

4. (349 + 56) - y = 12

To solve for y, we can start by adding 56 to 349:

(349 + 56) - y = 12

405 - y = 12

Next, we can subtract 12 from both sides of the equation:

405 - y - 12 = 12 - 12

393 - y = 0

Now, we can isolate y by subtracting 393 from both sides:

393 - y - 393 = 0 - 393

-y = -393

To make y positive, we can multiply both sides by -1:

(-1) * (-y) = (-1) * (-393)

y = 393

Therefore, the solution to the fourth equation is y = 393.

To summarize, the solutions to the given equations are:

1. X = 1217
2. y = -458
3. x = 898
4. y = 393
