17 - 6b = 23 - 4b b = -3 b = -6 b = 6 b = 3

17 - 6b = 23 - 4b

move -4b to the other side

sign changes from -4b to +4b

17-6b+4b= 23-4b+4b

17-2b= 23

move 17 to the other side

sign changes from +17 to -17

17-17-2b= 23-17

-2b= 23-17

-2b= 6

divide both sides by -2 to get +b

get b by itself

-2b/-2= 6/-2

cross out -2 and -2, divide by ,

-2

then becomes 1*1*b= b

b= 6/-2

divide by 2

6/-2= -3

2/2= 1

-3*1= -3

b= -3

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
