Please Help the question is below

A bag contains 24 blue and purple marbles. The number of purple marbles, p, is one less than four times the number of blue marbles, b. How many marbles are purple? Use the table to guess and check.

A). 5
B). 9
C). 15
D). 19

It said -1 and x 4 we do the opposite and add 1, but divide by 5 because you have to add 4 times p and p to get 5.

24 + 1 = 25

25 / 5 = 5

So P is 5. Double check

5 x 4 = 20 - 1 = 19

19 + 5 = 24

5 is the answer Hope this helps.

Step-by-step explanation:

answer: x

step-by-step explanation:

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
