Question

3x+y= - 8
4x+5y= 1о
find x and y​

Answer 1

Step-by-step explanation:

3x+y= -8

y= -8-3x --1

4x+5y=10

put y= -8-3x

4x+5(-8-3x)=10

4x+(-40-15x)=10

4x-40-15x=10

-11x=50

x= 50/-11=4.54

put x=4.54 in --1

y= -8-3(4.54)

y= -8-13.62

y= -21.62

(x,y)=(4.54,-21.62)

Answer 2

Answer:

3x+y= - 8

3x+y= - 8 4x+5y= 1о

3x+y= - 8 4x+5y= 1о find x and y
