(i) x+y=12. Find y if x=5. (ii) x+3y=-4 therefore x = ……… …. (Fill in the blanks.) (iii) Find x, if x+y=5 and x-y=7.

3 x + 5y = 12, 5x + 3y = 4 .

By how much is 5x-3y+4z greater than 5x-2y+2z+5

Find the value of p, if the lines 3 x + 4 y = 5 , 2 x + 3y = 4 , px + 4y = 6 are concurrent.

The line segment joining the points A (3,-4) and B (-2, 1) is divided in the ratio 1:3 at point P in it. Find the co-ordinates of P. Also, find the equation of the line through P and perpendicular to the line 5x – 3y = 4 .

Show that following system of linear equations is consistent 5x+3y=4, 3x+26 y=9,
