Answer: Samreen’s age is 10 Samreen’s brother’s age is 22
Explanation: Let s be equal to Samreen’s age. Let b be equal to Samreen’s brother’s age.
3s-8=b s+b=32
Substitute the first equation into the second as b s+b=32 s+(3s-8)=32 Open up the parentheses s+3s-8=32 4s-8=32 Add 8 to both sides 4s-8+8=32+8 4s=40 Divide both sides by 4 to isolate s 4s/4=40/4 s=10
Therefore, Samreen’s age is 10.
To find Samreen’s brother’s age, we substitute 10 into either of our original equations and solve for b.
s+b=32 10+b=32 Subtract both sides by 10 10+b=32-10 b=22
Therefore, Samreen’s brother’s age is 22.

From what we know in April and May combined Joe has collected 61 stamps (27+34=61). To then work out how many Joe collected in June you would take the 61 we know he has already got away from the grand total of 94 (94-61=33) this means in June he collects 33 stamps. Hope this helps :)
