Question

7 The model below represents the equation 2x + 3 = 11 Х X What is the first step in finding the value of x? OA. Add 11 cubes to each side of the model OB Subtract 3 cubes from each side of the model OC. Add 3 cubes to each side of the model OD. Divide the cubes equally among the 2 cups

Answer 1

2x+3 = 11

x= cups

To find the value of x:

2x+3 = 11

Subtract 3 fom boht sides of the equation:

2x+3-3 = 11-3

2x= 8

So, the first step is subtract 3 cubes from each side of the model.
