Answer:
Daughter age = 3 years
Step-by-step explanation:
Let x be the age of the women and y be the age of the daughter.
Given:
After five year the sum of the women and daughter age = 40
At present the sum of the women and daughter age
--------------(1)
So the sum of the present age is
The difference in their present age is 24 years.
Now we substitute x value in equation 1.
Therefore, the daughter age is 3 years.
The coefficient of y is 14 and the constant is 13.
You can find this by combining like terms first.
6x + 12y + 5 + 2y + 8
6x + 14y + 5 + 8
6x + 14y + 13
Now the coefficient is the number next to y. The constant is the number on its own.

Answer: x=4.41 y= -7.35
Step-by-step explanation:
Pretty basic just graph them using Desmos...
Showing your work you would need to get x on one side then y on the other.
Because 3y is positive I personally like to use that one first. The inverse operation of 3y is divide so you divide 3y by 3 and the 3s cancel out. Divide -22.05 by 3 and you get -7.35. Which is your y value.
Finding X is a bit more difficult, you need to divide by -5 which is the obvious inverse operation. So, -22.05/-5 and you get 4.41. Which is your X value.
