Question

What should be the value of "b" if the value of 5x - 2x + b is - 3 when x = - 1?

Answer 1

Answer:

Value of b = 0

Step-by-step explanation:

Given x=-1 ,

substitute x = -1 in the equation, we get

5x-2x+b = -3

=> 5(-1)-2(-1)+b=-3

=> -5+2+b=-3

=> -3+b=-3

/* Add 3 both sides of the equation, we get

=> -3+b+3=-3+3

=> b = 0

Therefore,

Value of b = 0

Answer 2

Answer:

b=0

Step-by-step explanation:

x=-1.......(given)

5x-2x+b=-3

Putting x=-1 in L.H.S

5(-1)-2(-1)+b=-3

-5+2+b=-3

-3+b=-3

Adding -3 on both the sides

-3+3+b=-3+3

Therefore,B=0
