Question 856880: The two straight lines 3y + 2x - 7 = 0 and 2 y = x - 7 intersect at the point P.
Find the coordinates of P. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! 2 x + 3 y = 7 .............1
Total value
1 x -2 y = 7 .............2
Eliminate y
multiply (1)by 2
Multiply (2) by 3
4 x 6 y = 14
3 x -6 y = 21
Add the two equations
7 x = 35
/ 7
x = 5
plug value of x in (1)
2 x + 3 y = 7
10 + 3 y = 7
3 y = 7 -10
3 y = -3
y = -1
P(5,-1)
