Question

-3x-4y=16;2x-3y=10 find the value of x and y​

Answer 1

Step-by-step explanation:

with this you pick your own "x" or "y" so,

x=-1

2x+3y =10

2(-1)+3y =10 substitute -1 for x

-2+3y =10 add 2 to both sides

3y =12 divide by 3

y =4 (-1,4)

x=2

2x+3y =10

2(2)+3y =10 substitute 2 for x

4+3y =10 subtract 4 from both sides

3y =6 divide by 3

y =2 (2,2)

choose any x then solve for y.
