Choose the equivalent system of linear equations that will produce the same solution as the one given below.
6x + 2y = -6

3x - 4y = -18
1) 12x + 4y = -12
15x = -30
2) 8x + 4y = -4
14x = -10
3) 6x - 8y = -36
-6y = -42
4) 6x - y = -15
3y = 9

Question

Choose the equivalent system of linear equations that will produce the same solution as the one given below.
6x + 2y = -6

3x - 4y = -18 
1)	12x + 4y = -12
15x = -30
	2)	8x + 4y = -4
14x = -10
	3)	6x - 8y = -36
-6y = -42
	4)	6x - y = -15
3y = 9

the answer is a option. but for these type of questions u have to check answer by solving each equations(options). so take time but give answer accurately.

What do you mean @raju0019 I dont really get this xD
Can you explain more plz

anonymous · Answer

see these type of question are simple but take little bit more time. first u solve given equa. and get x nd y values. then solve the option a. if both values are same as given equa. then stop nd move to another question. at last u ll get accurate answer. but u have to do practice....
