Question

Michael is 4 times as old as Brandon and is also 27 years older than Brandon.

Answer 1

let's represent Brandon's age by x and Michael is 4 times as old as Brandon so 4x andx+ 27. The equation is
4x=x+27 Therefore Brandon is 9 years old.
4x-x=x-x+27 4x=4*9=36
3x=27 x+27=9+27=36
3x/3=27/3
x=9

Answer 2

m=4b
m=27+b

subsitute
4b=27+b
minus b
3b=27
divide 3
b=9
sub back
4b=m
4(9)=m
36=m

michel=36 and brandon is 9
