1 answer:
Answer:
Jerry is 11.75 years
Step-by-step explanation:
Let us first set up an equation
Let jerry's age be x
4x - 11 = 36 (equation set)
Now we need to slove the equation and find the value of x that is Jerry's age
4x - 11 = 36
Transpose
4x = 36 + 11
4x = 47
x = 47 ÷ 4
x = 11.75 years
Jerry is 11.75 years
