4 0

You have the value for y, so you substitute that equation for y, times three because there are three yS.

So you have: 2x + 3y = 10

2x + 3 x 2x + 4 or 2x + 3(3x + 4)

so the answer would be B, 2x + 3(3x + 4)

Tatiana [17]

Answer:

Mikhail's age is 25 years old

Step-by-step explanation:

Let's make an equation: Say Mikhail is x, so Gabby would be 2*x=2x

If the sum of their ages equals 75, then x+2x=75, and x=2x=3x, so 3x=75.

75/3=25
