Answer:
Matt=25y, George =44y, Brad=30y
Step-by-step explanation:
Brad=B
Matt=M
George=G
Year=y
Then we have:
Matt=y
Brad is 5 years older than Matt⇒B=(M+5)y
George is 6 less than twice Matt's age⇒G=(2M-6)y
The sum=B+G+M=(M+5)+(2M-6)+(M)=90
So we can get age of Matt (M) By:
(M+5)+(2M-6)+(M)=90
4M-1=99
4M=100 dividing by 4
M=25 ⇒ Matt=25y
G=(2M-6)y=(2*25)-6=44 ⇒ George =44y
B=(M+5)y=25+5=30y ⇒ Brad=30y
hope this helps
