Question

solve the following pair of equation for x and y equation 3x+2y=5, 2x-3y=8
​

Answer 1

Step-by-step explanation:

3x + 2y = 5(multiply by 2)

2x-3y=8( multiply by 3)

6x+4y=10

-6x-9y=-24(after changing signs)

------------------

-5y=-14

y=14/5

3x+2(14/5)=5

3x+28/5=5

3x=5-28/5

3x=25-28/5

x=-2/15
