Question

3 3x+2y =12
5x-2y = 4

Answer 1

Answer:

for the first one: x=4

Step-by-step explanation:

In 3x + 2y = 12, let x = 0. Then 2y = 12 or y = 6, making the y-intercept (0, 6). Secondly, let y =0in3x + 2y = 12. Then 3x = 12 or x = 4, making the x-intercept (4, 0).

Answer 2

Answer:

x=2

y=3

Step-by-step explanation:

By the method of elimination

3x+2y =12 ............(1)

5x-2y =4 ............(2)

---------------

8x+0y =16

8x=16

x=2

----------

by eq.(1) we obtain

3(2) +2y=12

6+2y=12

2y=6

y=3

--------

Hope it would help
