Question

-3(x+y)+4(2x-3y)-(2x - y) where x = -2 and y = 1​

Answer 1

Answer:

-20

Step-by-step explanation:

Since it is given that x = -2 & y = 1,.

I substitute the given values in the given equation,.

 -3(x + y) + 4(2x - 3y) - (2x - y)

⇒ -3( (-2) + (1) ) + 4( 2(-2) - 3(1) ) - ( 2(-2) - (1) )

⇒ -3( -2 + 1 ) + 4 ( -4 - 3) - (-4 - 1)

⇒ -3(-1) + 4(-7) - (-5)

⇒ 3 - 28 + 5

⇒ -25 + 5 = 20

∴ The result is 20
