Answer:
BM = 26
Step-by-step explanation:
The vertical slash marks indicate that AM and BM are equal. So all you need to do is equate the AM = BM
3x - 4 = 4x - 14 Add 14 to both sides
3x - 4 + 14 = 4x Combine
3x + 10 = 4x Subtract 3x from both sides
10 = 4x - 3x Combine
x = 10
But that is not the answer. The question asks for BM
BM = 4x - 14 Substitute x = 10
BM = 4*10 - 14
BM = 40 - 14
BM = 26
