Question

3x + y = 7, 2x -lly = 3.​

Answer 1

Answer:

x = 16/7 , y = 1/7

Step-by-step explanation:

I'll solve this by elimination method

3x + y = 7      equation 1

2x -lly = 3.     equation 2

multiply eq 1 with 2 and eq 2 with 3

hence we get

6x + 2y = 14

6x - 33y = 9

changing signs of the last equation we get,

35y = 5

y = 1/7

putting in eq 1 we get,

3x +1/7 = 7

3x = 7-1/7

3x = 48/7

x = 48/7*3

x = 16/7
