Answer:

x = -3

y = 0

Step-by-step explanation:

Given equations :- 

-x + 2y = 3 ....... ( i )

2x - 3y = -6 ....... ( ii )

From ( i ) 

-x + 2y = 3

-x = 3 - 2y

x = 2y - 3 ........ ( iii )

From ( ii ) 

2x - 3y = -6

2x = -6 + 3y

$x = \frac{ - 6 + 3y}{2}$

........ ( iv )

Equating ( iii ) and ( iv )

x = x

$2y - 3 = \frac{ - 6 + 3y}{2}$

4y - 6 = -6 + 3y

4y - 3y = -6 + 6

y = 0

Putting value of y in ( iii )

x = 2y - 3

x = 2 ( 0 ) - 3

x = -3

Step by step solve for x the following problem... 34 - 5x + 2 (x - 2) = 15

xz_007 [3.2K]

34-5x+2(x-2)=15

34-5x+2(x)(2) (-2)=15

34-5x+2x-4=15

30-3x=15

30-3x-30=15-30

-3x=-15

-3x/-3=-15/-3

x=5
