Answer:

infinite solutions

Step-by-step explanation:

Simplify 3x-x-53x−x−5 to 2x-52x−5.

2x-5=2(x+2)-92x−5=2(x+2)−9

2 Expand.

2x-5=2x+4-92x−5=2x+4−9

3 Simplify 2x+4-92x+4−9 to 2x-52x−5.

2x-5=2x-52x−5=2x−5

4 Since both sides equal, there are infinitely many solutions.

Gabrielle's age is three times Mikhail's age. The sum of their ages is 20. What is Mikhail's age?
PtichkaEL [24]

Answer:

Mikhail is 5 years old

Step-by-step explanation:

Represent each member with a variable.

X= Gabrille

Y=Mikhail

X+Y=20 (sum of their ages is 20)

X=3y (Gabrille is 3 times Mikhails age)

Substitute 3Y into the first equation (simultaneous equation)

. 3y+y=20

. 4y=20 (divide both sides by 4)

y=5

To check your answer.

X+5=20

X=20-5

X=15

15 is 5 times 3.
