Question

Find x & y by elimination method : 2x = 5y + 4 3x - 2y + 16 = 0​

Answer 1

Step-by-step explanation:

2x-5y=4.............eq(1)

3x-2y=-16.........eq(2)

eq(1)*3

eq(2)*2

eq(1)-(2)

6x-15y=12

6x-4y=-32

-11y=44

y=-4

substitute in equal( 1)

2x-5(-4)=4

2x+20=4

2x=-16

x=-8

Answer 2

Answer:

multiply( 2x-5y+4)×3 and (3x-2y+16)×2 then subtract both equation you get y than put the value of y in any equation you get x
