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.
I hope this helps! Please comment if you have any questions :)
