When do you have a solution and when do you have a solution set

( the set of all variables that makes the equation true.)

Step-by-step explanation: the solution set 2y + 6= 14 is {4}, because 2(4) + 6=14.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
