Question

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

Answer 1

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

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
