Question 1044042

Michael is 12 years older than Brandon. Seventeen years ago, Michael was 4 times as old as Brandon.
How old is Michael now?

Hi! i tried to and came out with 

m= b+ 12                m being michael's age and B being Brandon's age
m= 4b + 17

I dont know where else to go with these. they could be wrong
thank you so much for your help!!
<pre>m = b + 12 ----- Correct      m = 4b + 17 ----- Incorrect
b = m - 12 ------- eq (i)
m - 17 = 4(b - 17) ------ eq (ii)
m - 17 = 4(m - 12 - 17) ----- Substituting m - 12 for b in eq (ii)
m - 17 = 4(m - 29)
m - 17 = 4m - 116
m - 4m = - 116 + 17
- 3m = - 99
m, or Michael is: {{{highlight_green(matrix(1,4, (- 99)/(- 3), or, 33, years-old))}}}
