Question

Solve the problem using elimination method​

Answer 1

Step-by-step explanation:

2x=5y-4=>2x-5x-4=0-----(1)eq

3x-2y+16=0----(2)eq

then

2x-5x-4=0_____×(3)= 6x-15x-12=0___(3)eq.

3x-2y+16=0___×(2)=6x-4y+32=0___(4)eq

from equation (3) and (4)

6x-15y-12=0

6x-4y+32=0

(-) (+)(-)

____________

0-11y-44=0

-11y=44

y=-4

substitute y=-4 in eq( 2)

3x-2(-4)+16=0

3x+8+16=0

3x+24=0

3x=-24

x=-8
