Answer:
Step-by-step explanation:
let me see if I can explain this...
3 + 5 = 8....those 2 numbers added together equals the total(8)...if u take the total(8) and subtract one of the numbers, it gives u the other number.
8 - 5 = 3 and 8 - 3 = 5
here's another one...
30 + 60 = 100
100 - 30 = 60 and 100 - 60 = 30
R-9s=2 add 9s to both sides
r=2+9s making 3r-3s=-10 become:
3(2+9s)-3s=-10 perform indicated multiplication on left side
6+27s-3s=-10 combine like terms on left side
6+24s=-10 subtract 6 from both sides
24s=-16 divide both sides by 24
s=-16/24
s=-2/3, making r-9s=2 become:
r-9(-2/3)=2 perform indicated multiplication on left side
r+6=2 subtract 6 from both sides
r=-4
So s= -2/3 and r= -4
