Um depends are you trying to get the x byitself?
Answer:
2,-5,-12,-19,-26
Step-by-step explanation:
-7n +9
-7(1) +9 = 2
-7(2)+ 9= -5
-7(3)+9 = -12
-7(4)+9 = -19
-7(5)+9 = -26
#7 is 3
#8 is 4
#9 is 4
#10 is 3
#11 is 5
#12 is 3
U can use the second last one
X + 90 = 2x + 40
Do the operation:
3, 16, 24 | 2
3, 8, 12 | 2
3, 4, 6 | 2
3, 2, 3 | 2
3, 1, 3 | 3
