Answer 1

Hey

Here is your answer,

Equation 1 : -a x 20 + (b-a)x20=0
Simplify it.
-20a +20b -20a =0
20b -40a =0
Divide the equation by20
b -2a =0-------------- eq.1

Equation 2 : -b x 10-a x 20+10=0
simplify it.
-10b -20a +10=0
-10b -20a =-10
10b +20a =10
Divide the equation by 10,
b + 2a =1-------------eq.2

Solving both the equations by elimination method,

b-2a=0
b+2a=1
-----------
2b=1
b=1/2

Substitute the value of b in equation 1,
b-2a=0
1/2-2a=0
1-4a/2=0
1-4a=0
1=4a
a=1/4

Hope it helps you!
