Answer:
Both sides are equal, true for all 'b'
Step-by-step explanation:
Add similar elements: b + 0.17b = 1.17b
1.17b = 1.17b
Multiply both sides by 100
1.17b * 100 = 1.17b * 100
Refine
117b = 177b
Subtract 117b from both sides
117b - 117b = 117b - 117b
Refine
0 = 0
Both sides are equal, true for all 'b'
