Question

The equation 2x + 3 = 5 is modeled below. What is the first step in finding the value of x?

A) Add 3 to each side of the model
B) Subtract 3 from each side of the model
C) Add 5 to each side of the model
D) Subtract 5 from each side of the model

Answer 1

The first step in finding the value of x in the equation 2x + 3 = 5 is to subtract 3 from each side of the equation.

Step-by-step explanation:

The first step in finding the value of x in the equation 2x + 3 = 5 is to subtract 3 from each side of the equation. This step is necessary to isolate x on one side of the equation.

Subtracting 3 from each side of the equation gives us 2x = 5 - 3, which simplifies to 2x = 2.

By subtracting 3 from each side, we have simplified the equation and can now move on to further simplifications or solve for x.
