-2x - 13 = -3x - 5
Step 1: Combine like terms
x's go with x's (-2x and -3x). To do this add 2x to both sides
(-2x + 2x) - 13 = (-3x + 2x) - 5
(0) - 13 = (-x) - 5
- 13 = -x - 5
normal numbers go with normal numbers ( -13 and -5). To do this add 5 to both sides
(- 13 + 5) = -x + (- 5 + 5)
-8 = -x + (0)
-8 = -x
Step 2: Isolate x by dividing -1 to both sides (this will take the negative sign away from the x)

8 = x
x= 8

Answer:
D
Step-by-step explanation:
The weight of the cupcake in an expanded form is 3.5 * 10⁻¹ lb
<h3>How to determine the weight?</h3>
The weight is given as:
Weight = 0.35 lb
Remove the unit
Weight = 0.35
Multiply the weight by 1
Weight = 0.35 * 1
Express 1 as 10/10
Weight = 0.35 * 10/10
Evaluate the product
Weight = 3.5 * 1/10
Express 1/10 as an exponent
Weight = 3.5 * 10⁻¹
Return the unit
Weight = 3.5 * 10⁻¹ lb
Hence, the weight in expanded form is 3.5 * 10⁻¹ lb
