Answer:
Answer : Gina's age is 19 years.
Step-by-step explanation:
Kamal is 17 years older than Gina. Gina is 3 years younger than Rachelle.
Let Gina's age be x years
So Kamal’s age will be = x + 17
Rachelle’s age = x + 3
the sum of their ages is 77, Accordingly
x + x + 17 + x + 3 = 77
3x + 20 = 77
3x = 77 - 20
3x = 57
x = 57/3
x = 19
Thus Gina's age is 19 years,
Kamal’s age x + 17 = 19 + 17 = 36 years
Rachelle’s age x + 3 = 19 + 3 = 22 years
Gina = 19 years old
A. Alright, we want to multiply one equation by a constant to make it cancel out with the second. Since the first equation has a "blank" y, let's multiply the first equation by <em>2</em>.
3x-y=0 → 2(3x-y=0) = 6x - 2y = 0
5x+2y=22
The answer for this part would be: 6x - 2y = 0 and 5x + 2y = 22
B. So now we combine them:
6x - 2y = 0
+ + +
5x + 2y = 22
= = =
11x + 0 = 22 ← The answer
C. Now that we have the equation 11x = 22, we solve for x
11x = 22 ← Divide both sides by 11
x = 2 ← The answer
D. Now that we have x=2, we plug that back in to 5x+2y=22 and solve for y:
5(2)+2y = 22
10 + 2y = 22
2y = 12
y = 6
<u>Therefore, the solution to this problem is x = 2 and y = 6</u>

I can't include a picture but it will be the same shape except it will be flipped over and will look a bit like differently angled packman with the back of the mouth apart the same distance, with the mouth "pointier" part of it one line away from the red line from the other side.... Oof sorry if this didn't help, I tried my best...
Step-by-step explanation:
From the "point" of the blue triangle, go diagonally SE 2 spaces. From there, draw a straight line to the right for 3 spaces. From there, draw upwards two spaces, and then connect those two lines into a triangle.
