Answer:
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
