X- 2y = 3
3x - y = 2

Answers

Answer: x = 1/5 and y= -7/5

Step-by-step explanation: Let's solve your system by elimination.

Multiply the first equation by -3,and multiply the second equation by 1.

-3 (x - 2y = 3)

1 (3x - y = 2)

Becomes:

-3x + 6y = -9

3x -y = 2

Add these equations to eliminate x:

5y = -7

Then solve 5y = -7

5y/7 = -7/5

y = -7/5

Now that we‘ve found y, let’s plug it back in and solve for x.

Write down an original equation:

x - 2y = 3

Substitute -7/5 for y in x - 2y = 3:

x - 2 (-7/5) = 3

x + 14/5 = 3

x 14/5 + -14/5 = 3 + -14/5 (Add (-14)/5 to both sides)

x = 1/5

Answer:

x = 1/5 and y = -7/5

Round 45,122 to the nearest ten thousand

Answers

Rounded to the nearest 10,000, 45,122 is 50,000. This is because the 5 has been reached and so it is rounded up.

To round to the nearest ten thousand, we look at the last four digits. If these digits are 5000 or greater, then we round the thousands digit up, and if they are less than 5000, then we round down, keeping the ten thousand's digit the same.

The question is asking to Round 45,122 to the nearest ten thousand .

The last 4 digits are 5122.

This is greater than 5000.So we round up .

45,122 to the nearest ten thousand is 50,000.
