For what value(s) of w does the equation 7 + 3x - 1 = w(x + 2) have infinitely many solutions?

w=3

Step-by-step explanation:

7 + 3x - 1 = w(x + 2)

Solve for w

Distribute

7 + 3x - 1 = wx + 2w

Combine like terms

3x+6 = wx+2w

For this to have infinite terms

3x = wx   and 6 = 2w

3x = wx

Divide by x

3 =w  

and 6 = 2w

Divide by 2

6/2 = 2w/2

3 =w

When w = 3, there will be infinitely many solutions

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

eve and marks ratios are equivalent
