X - y/2 = 4
x - 4 = y/2
2(x - 4) = y
2x - 8 = y.....so we sub in 2x - 8 in for y in the other equation

3x - 2y = 11
3x - 2(2x - 8) = 11
3x - 4x + 16 = 11
-x = 11 - 16
-x = -5
x = 5

2x - 8 = y
2(5) - 8 = y
10 - 8 = y
2 = y

It has one solution and it is (5,2)

Anybody trying to help me do this I’m stuck and it’s hard
ahrayia [7]

<u>Answer:</u>

<em>Below!</em>

<u>Step-by-step explanation:</u>

<u>Part-1: Find the mixed fraction form of 9/3</u>

<em>3 goes into 9 about 3 times because 3 x 1 = 3. If we used 3 x 2, that would exceed the limit '4'. So, 3 will be the whole number. Since we have no remainder, we must reduce the whole number to 2. We know that 1 = 3/3, hence, 2 3/3 is the mixed fraction.</em>

  • 9/3 = 3/1
  • = 2 3/3

Hence, the answer 3 or 2 3/3 in mixed form.

<u>Part-2: Find the mixed fraction form of 4/3</u>

<em>3 goes into 4 about 1 time because 3 x 1 = 3. If we used 3 x 2, that would exceed the limit '4'. So, 1 will be the whole number. We also have a remainder. That remainder will be the fraction.</em>

  • => 4/3 = 1 + 1/3
  • => 1 1/3

Hence, the answer in mixed fraction form is 1 1/3.

<u>Part-3: Find the mixed fraction form of 16/7</u>

<em>7 goes into 16 about 2 times because 7 x 2 = 14. If we used 7 x 3, that would exceed the limit '16'. So, 2 will be the whole number. We also have a remainder. That remainder will be the fraction.</em>

  • => 16/7 = 2 + 2/7
  • => 2 2/7

Hence, the answer in mixed fraction form is 2 2/7.
