4 -8=9-6X
Move -6X to the other side, sign changes from -6X to +6X.
4X+6X-8=9-6X+6X
4X+6X-8=9
10X-8=9
Move 8 to the other side, sign changes from +8 to -8.
10X-8=8=9+8
10X=17
divide by 10 for both sides
10X/10=17/10
X=17/10 or X= 1 7/10
Answer: X=17/10 or X= 1 7/10

Answer:
This is important because, the first few numbers might seem to follow a pattern but subsequent numbers might reveal a change in the rule.
Step-by-step explanation:
When studying patterns it is important to evaluate all the figures holistically instead of drawing conclusions based on just the first few numbers because there might be a change in what we felt was obvious on close observance of all the numbers. For example, observe the pattern;
2,4,6, 10, 14, 18, 20, 22, 24
The first two numbers show the addition of two. If a person decides to add 2 to all the figures, he would be wrong because after the first three figures, he would have to add 4 to the numbers.
If you have 10 1 dollar bills and you are buying something that is $5, you would divide your money in half to get $5
