Answer:  x=1;y=1 or (1,1)

Step-by-step explanation:

You can apply the Method of substitution.

Knowing that  x = 2y - 1 (second equation), you can substitute it into the first equation and solve for the variable y:

2x+y=3\\2(2y - 1)+y=3\\4y-2+y=3\\5y=3+2\\5y=5\\y=1

Now you need to substitute y=1 into the second equation x = 2y - 1 to calculate the value of the variable x. Then:

x = 2(1) - 1\\x=2-1\\x=1

Then, the solution is:

x=1;y=1 or (1,1)

What is 76 rounded to the nearest hundred
Citrus2011 [14]
100. When rounding to the hundreds place, you must consider the value of the digit in the tens place. If the digit in the tens place is 5 or greater, the digit in the hundreds place increases by 1. If the digit in the tens place is 4 or less the digit in the hundreds place remains the same. In this case, the number in the hundreds place was originally zero.
