Question

solve 7x - 2y = 3 and 11x - 3/2y = 8 using elimination method

Answer 1

Step-by-step explanation:

$7x - 2y - 3 = 0$

is the first equation...........1

$22x - 3y - 16 = 0$

is our second equation..........2

now, multiply eq1 with 3 and eq2 with 2 on both sides.

$21x - 6y - 9 = 0$

will be the first equation........3

$44x - 6y - 32 = 0$

will be the second equation..........4

now subtract eq3 and eq4.

$23x - 23 = 0$

$x = 1$

now, put x in eq1,

$7(1) - 2y - 3 = 0$

$2y = 4$

$y = 2$

hence,

$x = 1$

and

$y = 2$
