Answer:
(x+1)(x-6)
Step-by-step explanation:
Answer:
a) Let Kim's age be k, then Kim's sister's age is k/2
k+
=24
b) k+
=24
1
k=24
k=16
=8
Kim's age is 16 while her sister's age is 8.

Hey!
To solve this problem, we must subtract one over three from both sides of the equation. This will give us x on its own.

Step-by-step explanation:


To solve a system of equations, we can add the two equations and solve for one of the remaining variables -- let's try to eliminate the
variable when we add the two equations together.
Right now, there's a
term in the first equation, and a
term in the second equation, so if we add those together, we'll be able to eliminate the
variable altogether and solve for
.
However, when we also have a
term in the first equation and
term in the second equation, so adding these together will also eliminate the
term, leaving a
on the left-hand side of the equation.
If we add the two numbers on the right side of the equation, we get
, which does not equal
, meaning there are no solutions to this system of equations.
