So I first did m=b+12, representing Micheal's Age. Then I wrote the equation m-17=4b, representing how 4 times Brandon's age was equal to Micheal's age 17 years ago. So, I plugged my m into the 2nd equation, and got this: b+12-17=4b-5=3b b=-5/3 Obviously that's wrong, but I don't understand how I could have constructed the equation incorrectly.Therefore, given pair of linear equations is con-sistent. Question 6. Check graphically whether the pair of equations 3x – 2y + 2 = 0 and \(\frac{3}{2}\)x – y + 3 = 0, is consistent.
