Question

(iv) 2x + 3y = 12; 2x = 3y​

Answer 1

Answer:

2x+3y=12-----1

2x=3y-----2

put eq 2 in 1

3y+3y=12

6y=12

y=2

put value of y in eq 2

2x=3(2)

x=3

here is your answer

x=3,y=2

Answer 2

Step-by-step explanation:

2x+3y=12.....i

2x-3y=0.....ii

From equation i.....

2x=12-3y

x=12-3y/2......iii

From equation ii.....

2x-3y=0

2(12-3y/2)-3y=0

y=2

Putting the value of y in equation ii..

2x-3y=0

2x-3(2)=0

x=3

Therefore, y=2, x=3....

This is in Substitution Method...
