Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

x = 28/9      y=7/5

Step-by-step explanation:

3/2x + 5/3y =7

so it will become after lcm and cross multiplication 9x + 10y = 42

Now 9x + 10y = 42 -------1

        9x - 10y = 14

so +10y will cancel with -10y

and after adding 18x = 56 after solving x = 28/9

Now put x=28/9 in 1

Then 9(28/9) -10y =14

y= 14/10

so y=7/5
