Equation R: -3y = -3x - 9
Equation S: y = x + 3
Replace y in Equation R with equation S:
-3(x+3) = -3x - 9
Use distributive property:
-3x -9 = -3x -9
Because both sides of the equation are identical x can be any number and they would still be equal.
This means there are Infinite solutions.
So the other equation is
2.5 times as many kilos of rasins than sunflower seeds or
rasin kilos=2.5 times sunflower seed kilos
r=2.5s
the 2 equations are
12s+6r=108 and
r=2.5s
you can simplify the first equation (that sometimes helps)
undistribute the 6 from both left side
6(2s+r)=108
divide both sides by 6
2s+r=18
now use r=2.5s and subsitute 2.5s for r in first equation
2s+2.5s=18
4.5s=18
divide both sides by 4.5
s=4
subsitute
r=2.5 times s
s=4
r=2.5 times 4
r=10
rasins=10 kilos
sunflower seeds=4 kilos
