Answer:
a = 5
Step-by-step explanation:
3(a - 4) + 1 = 9 - a Distribute the 3 into a-4
3a - 12 + 1 = 9 - a Combine like terms
[-12 and 1]
3a - 11 = 9 - a Add 11 to both sides to isolate 3a
+11 +11
3a = 20 - a Add a to remove it and have all a
+a +a
4a = 20 Divide by 4 to only have a
/4 /4
a = 5
The answer would be -6a^5

1490/2 = 745
a = 745-190/2 = 650
b = 745+190/2 = 840
b-a = 190, 840-650 = 190
a+b = 1490, 650+840 = 1490
