Answer 1

Step-by-step explanation:

4x+3y=21

4x+2y=16

If we add both the equation:

4x + 3y = 21

4x + 2y = 16

(-) (-) (-)

4x + 3y = 21

-4x - 2y= -16

=> 0+1y= 5

y=5

substituting Y in eq 1

4x+3y=21

4x+3(5)=21

4x+15=21

4x=21-15

4x=6

x=1.5

x=1.5 and y=5

Answer 2

Answer:

x= 1.5

y=5

Step-by-step explanation:

do equation 1 and 2 then,

subtract the equation
