Question

Simplify:-

-3 (x + y) + 4 (2x - 3y) - (2x - y)

[x = -2, y = 1]​

Answer 1

Answer:

-20

Step-by-step explanation:

-3( x + y ) + 4 ( 2x - 3y ) - ( 2x - y )

= -3x  - 3y + 8x - 12y - 2x + y

= -3x +8x -2x -3y -12y +y

= 3x - 14y

= 3×(-2) -14×1                       [x = -2, y = 1]​

= -6 -14

= -20

Answer 2

Answer:

$-20$

Step-by-step explanation:

• Given expression:

$-3(x+y)+4(2x-3y)-(2x-y)$

• To solve the given expression, we need substitute the values of $x,y$

• On substituting the values of $x,y$ in the given expression, we get

$-3(x+y)+4(2x-3y)-(2x-y)$

$=-3(-2+1)+4(2(-2)-3(1))-(2(-2)-1)$

$=-3(-1)+4(-4-3)-(-4-1)$

$=3+4(-7)-(-5)$

$=3-28+5$

$=8-28$

$=-20$

Hence, the answer is $-20$.
