A (2, 3)
Step-by-step explanation:
2x - y = 1
4x + y = 11.
By adding both equation we got :
6x = 12
x = 12/6 = 2
Put value of x in first equation
2(2) - y = 1
4 - y = 1
y = 4-1 = 3
Points are (2,3)
Answer A.
Explanation:
{2x - y = 1
{4x + y = 11 Â Â Â Â Â Â Â Â (+)
2x + 4x - y + y = 1 + 11
6x = 12 Â Â Â Â Â Â Â Â Â | : 6
x = 2
{x = 2
{2 · 2 - y = 1
{4 - y = 1 Â Â Â Â Â Â | + y
{4 = 1 + y       | - 1
