Answer:
1) let the larger number be x and the smaller is y
2) 9x + 2y = 6
3x - y = 7
3) 9x+2y=6 and 9x -3y = 21
5y = -15
y= -3
5)
3x=4
x=4/3
Given |u| = 1 and a = 45, you can determine the component form of u.

In same way you can find component form of u+v

By property of vector subtraction:
v = (u+v) - u

Answer:
Let x= the ones digit
Then x+5=the tens digit
Hence the equation is: 10(x+5)+x=x+5+x+63
10(x+5)+x=x+5+x+63
10x+50+x=2x+68
11x+50=2x+68
-2x-50 -2x-50
---------------------
9x=18 Divide both sides of the equation by 9
x=2
Hence the number is 10(2+5)+2=10(7)+2=70+2=72.
