xxxxxxxxxxxxxxx

-7x-y=-19 xxxxxx

subtracting xxx equation ..(i) from equation ..(ii) we xxxx

xxxxxxxxxxxxxxxxxxxx

=>-7x-y+7x-4y=-25

=>-5y=-25

=>5y=25

=>y=25/5

xxx us xxxxxxxxx x xxxxxx

-7 x x x x = 6

xx x - y = - 19 multiply xxxx xxxxxxxx with xxxx

xxxxxxxxxxxxxxxxxx

-7 x x 4 y = x

x x + y x xx add both xxxxxxxxx

==================

x x x 5 x = 25 xxxxxx both sides xx xxx equation by x

y x 25/5 x 5

xxxx for x we xxxx xx e.g. xxx xxxxxx xxxxxxxx and solve it for xx

xx x x x x - 19 add y xx both xxxxx xx the equation

==================

-7 x = - 19 x y xxxxxx both sides xx xxx equation xx -7

x = (- 19 x y)/(-7) x xxx x xxxx

xxxxxxxx y=5:

x x (19 - xxxx = (19 - 5)/7 = xxxx = 2

xxxxxxxxx xxxx solution is:

x x xx x = xx

xxxx at xxx diagram attached. At x = 2 xxx x x x xxxx lines xxxxxxxxxx

The equation xxxx

-7 x x + 4 * x x 6

xx x x x y = xxx

We xxxxxxxx xxx second xxxxxxxx xxxx the xxxxx one xxx xx have:

-7 * x - xxxx * x x x * x x (-y) = x x xxxxx =

-7 x x + 7 * x x 4 * x x x x x + xx xx

x

xx xxxxxx out the common factor x from xxx xxxxx two xxxxx and xxx xxxxxx factor y
