Lets say you are trying to find the X in this equation:
2x-8=18 1. find a way to leave the 2x by itself.
2x=26 2. since the 8 is a negative (-8), becase it has a subtraction sighn , you add it to the 18 on the opposite side so yu have the 2x by itself.
3. Now you have to divide since there is nothing else you can do.
You divide 26 by two and then 2 by 2. now you have x=13.
This technique goes the same for if you have more that just two numbers that dont have a variable, but you said two step, so this is a prime example. I hope this helped. :)
The factored form of the given expression x² + x - 2 is ( x - 1 )( x + 2 ).
<h3>What is the factored form of the given expression?</h3>
Given the expression;
x² + x - 2
Consider the standard form ax² + bx + c compared to the given expression;
Now, we find a pair of integers whose product gives the value of c which is -2 and whose sum gives the value of b which is 1.
The integers are -1 and +2.
Check
-1 × 2 = -2
-1 + 2 = 1
Now, we write the factored form using these integers.
( x - 1 )( x + 2 )
Therefore, the factored form of the given expression x² + x - 2 is ( x - 1 )( x + 2 ).

Wouldnt this be something like x and y squared
Answer:
x = 3.0
Step-by-step explanation:
0.4(x -4) +0.6x = 1.4
0.4x -1.6 +0.6x = 1.4 . . . . eliminate parentheses
x = 3.0 . . . . . . . . collect term, add 1.6
