In the system of equations above, and are constants. If the system has an infinite number of solutions, what is the value of ?A)60B)1C)D) Loading... Page navigation ← Daily PWN 098 Daily PWN 100 →
Maybe faster? Since “infinite solutions” means they are the same line, we can just set the 2 equations equal to each other, no? For my solution, I multiplied each term in first equation by 15 to get rid of fractions, multiplied each term in second equation by 7 to rid fractions, then set equations equal. You could then see that -7b must = -60, so set 7b = 60 and solve for b.
Thats how I did it
