Question

Find the value of this expression if x = -2 x + 3 x-1 Enter the correct answer OOB C

Answer 1

Answer:

i)1

ii)-3

Step-by-step explanation:

If x=-2

then to evaluate x+3 and x-1 we place the value of x in both its place:

i)x+3

= -2+3

=1

ii)x-1

=-2-1

=-3

Answer 2

For this case we must find the values of the expressions given taking into account that the variable "x" is equal to -2. ($x = -2$)

Expression 1:

$x + 3 =\\-2 + 3 =$

Different signs are subtracted and the sign of the major is placed.

$-2 + 3 = 1$

Expression 2:

$x-1 =\\-2-1$

Equal signs are added and the same sign is placed.

$-2-1 = -3$

ANswer:

1,-3
