Answer:
-1
Step-by-step explanation 4 - 3x= 2x+9
take x in a side and the numbers in the other side then 4-9=2x+3x................-5=5x.....x=-1
Answer:
The pattern that can be created with the rule n x 2 + 1 is 1, 3, 5, 7, 9, 11.
I hope this helps.
X + 18 = 5x - 38
x - x + 18 = 5x - x - 38
18 = 4x - 38
18 + 38 = 4x - 38 + 38
56 = 4x
56/4 = 4x/4
14 = x
