7B + 4 = 7B - 3
We need to solve for B
Let's add 3 in both sides:
7B + 4 = 7B - 3
7B + 4 + 3 = 7B - 3 + 3
7B + 7 = 7B
Let's subtract 7B from both sides:
7B + 7 = 7B
7B - 7B + 7 = 7B - 7B
7 = 0
7 = 0, which is impossible. 7 can never be 0, and 0 can never be 7.
So the equation have no solution.
Answer:
........ true ...
obviously -3 is greater than -4
470 miles in 2 hrs......470/2 = 235 per hr
