1. Strategy I would use
Let me show you an strategy:
<u>Break apart strategy:</u>
The strategy of break apart numbers (Place Value) consists in the decomposition or separation of numbers. We can break both numbers down to place value and add each, starting with the largest or keep one number intact and only break second number down by place value and adding each place. Anyway, using this strategy we have:
2 + 8 = ?
2 breaks into 1 plus 1 (1 + 1), 8 breaks into 4 plus 4 (4 + 4), so by associative property:
(1+4)+(1+4) = 5+5=10
2. Explain how I decided.
This strategy is good to add larger numbers. In this way, we may break larger numbers up into hundreds, tens, ones, then add. This is an easy way to find additions.

Answer:
b. fundamental arithmetic
Step-by-step explanation:
While fundamental arithmetic is required when solving linear equations, the use of it is not a named <em>method of solution</em>.
"Substitution", "Elimination", and "Graphing" are named methods of solving linear equations. Sometimes the line can be blurred between substitution and elimination, but these methods generally involve distinct sets of steps (which include the use of fundamental arithmetic).
Answer:
X=8
Step-by-step explanation:
46+9x-8=14x-2
46-8+2=14x-9x
40=5x
8=x
