Is C and D because 10x^2-6x^2=36+64
4x^2=100
x^2=25
x= -5 or 5
Divide both numbers by 13/90
13/90x = 130
÷13/90 ÷13/90
x= 900

Answer: Kate = 40/3 Her father = 50
Step-by-step explanation:
Let Kate's age in the present be K
And Kate's father's age in the present be F
3(K+5) = F+5
6(K-6) = F-6
Rearrange the first equation to get
3K+15 = F+5
3K+10 = F
Substitute that into the second question
6K-36 = 3K+10-6
3K = 40
K = 40/3
So F = 3*40/3+10 = 50
