x=5

Answer 2

Step-by-step explanation:

we can solve this using substitute method

3x = 30 - 5y

x = (30 -5y) /3

x= 10 -(5y/3)

now putting value of x in other equation

5(10-(5y/3)) - 3y = 16

50 -25y/3 -3y = 16

taking lcm as 3

(150 -25y-9y)3 = 16

150-25y-9y = 54

150-34y = 54

-34y = 54-150

34y = 96

y = 96/34
