Except there are values you want to substitute into the expression, this is what your answer looks like:
Answer: Elaine=13 years old Tyler=21 years old
Step-by-step explanation:
Let x = Elaine's age, so her brother Tyler's age = x+8
Elaine+Tyler=34
x+(x+8)=34
2x+8=34
2x=26
x=13
Elaine=13 years old
Tyler=21 years old
1/2 x 3/4
1 x 3 / 2 x 4
= 3/8
