Answer:
3.s is 3 times the age of Sydney's which is equals to Luke age + 5
Step-by-step explanation:
Given Sydney’s age, s
and also Luke is 5 years younger than 3 times Sydney’s age.
Sydney's 3 times age is 3.s
Luke age = Sydney's 3 times age - 5
Luke age=3.s-5 ⇒ 3.s = Luke age + 5
Hence, 3.s is 3 times the age of Sydney's which is equals to Luke age + 5
Is this what you mean this is what i understood.
X-4=10;4x+1=57
First equation solve for x.
X-4=10
Add 4 both sides
X=10+4
X=14
Second equation substitute your x answer into second equation to make both sides equal.
4x+1=57
4(14)+1=57
56+1=57
57=57
