Explanation:
When we have variables on both sides we look for the coefficient that is lower than the two and reverse the sign.
Example:
1x+ 4 = 2x+3
We reverse 1x sign because it is lower so we will be subtracting
2x-1x = 1x
1x+3=4
We would then solve for x.

Let's begin to solve! </span>
Step 1:
You would look for the coefficient or variable that is less and reverse the sign.
In this question the lower number is -x and so we would reverse the sign to add.
x+x= 2
Step 2:
We now have
2x+3 = -5
Step 3:
We will subtract 3 to -5 to find X
-3+-5= -8
Step 4:
2x = -8
Divide both sides by two fo find x
Our answer:
-
Summary:
We first looked for the lower coefficient (in this case variable). We then flipped the sign and solved for x.
