4. what is the y value of the solution to the
to the system of equations shown below?
s 4x + 3y = 10
| 3x - 2y = 5

x=35/17, y=10/17. (35/17, 10/17).

Step-by-step explanation:

4x+3y=10

3x-2y=5

3(4x+3y)=3(10)

-4(3x-2y)=-4(5)

12x+9y=30

-12x+8y=-20

17y=10

y=10/17

4x+3(10/17)=10

4x+30/17=10

4x=10-30/17

4x=170/17-30/17

4x=140/17

x=(140/17)/4

x=(140/17)/(1/4)

x=140/68

simplify

x=35/17

answer: a.   one is a factor of every whole number since every number is divisible by itself.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
