Question

X by 2 +2 y by 3 equal to negative 1 and x minus y by 3 equal to 3 by elimination method​

Answer 1

Answer:

Hey mate here is ur answer↓↓

_x_ + _2y_ = -1 ––>✓(1)[× eq(1) by 6]

2 3

x-_y_ = 3 –—>✓(2) [× eq(2) by 3]

3

°•° eq(3)→ 3x+4y= -6

°•° eq(4)→ 3x-y= 9

subtract eq(3)&(4)

3x+4y=-6

(-)3x-(+)y=(-)9

0+5y=-15

y=3{-15}→eq(5)

5

USE EQ(5)IN EQ(4)[for easy calculations]

3x-3=9

3x=9-3

x=_6_ =2

3

•^• x=2,y=3
