Question

SOLVE BY ELIMINATION METHOD
3x + 10y = -14
8x -3y = 22​

Answer 1

Answer:

3x+10y=-14------(i)

8x-3y=22--------(ii)

multiply eqn. 1 with 8 and eqn (ii) with 3

24x+80y= -112----(iii)

24x-9y=66----(iv)

subtracting eqn. (iv) from eqn. (iii)

89y=-178

y=-2

put in (i)

3x-20=-14

3x=6

x=2
