Answer:
3(x+6)
Step-by-step explanation:
Parenthesis after a number typically means multiply, so 3 times the sum of an unspecified number (x), plus 6 would be 3 (x+6)
The equation of that is y=kx
Substitute it in and you get
20=6k
Divide 6 on both sides
k=3 1/3
Then since it asks what is the value of y when x is 24 use k in the equation
y=3 1/3*24
so y=80 is the answer
To solve the equation undo the operations on the variable in reverse of PEMDAS
this eliminates "S" subtract 7 with "A" add 7
Simplified both sides
this eliminates "D" divide by 5 with "M" multiply by 5
