Distribute to each
(-4)(-6+4v+2u)=-4(-6)-4(4v)-4(2u)=24-16v-8u
It is 20
39+1
38+2
37+3
36+4
35+5
<span>Until you get to 20+20</span>
So there are three variables, rs2 label x, rs5 label y, rs10 label z
Lets write equeations using these variables.
x+y+z=120 (<span>A bag has a total of 120 notes)
2x+5y+10z=760 (total value)
2x+5*2y+10z=960 (twice as many rs5)
3 variables, 3 independent equations will give solution. There are a fair few ways to solve this. </span>
The answer is: A
I hope it’s helps you :)
