Ihave a im dumb veryyy dumb! so maybe you can me with my math? pretty < 3

i think the answer is b)

step-by-step explanation:

b is the final answer! : )

3. y = x+5 and 2(y +10) = x

Step-by-step explanation:

The variables are defined in the problem statement. The second equation, 2(y+10)=x, says, in effect, ...

... In 10 years, twice John's age will equal Mary's age now.

There is no corresponding statement in the given problem, so this equation is useless for finding the solution.

The solution to the last system of equations is (x, y) = (-30, -25)—not a viable solution to any age problem.
