-5 + 6d + 3 = 34
-2+6d=34
Add 2 to both sides
6d=36
Divide both sides by 6
6d/6=36/6
d=6
Check:
-5 + 6d + 3 = 34
Substitute d=6 into the equation
-5+6(6)+3=34
-5+36+3=34
31+3=34
34=34
Hope this helps! :)
The number of cups of sugar in the recipe is 2/3 (0.67) times the number of cups of oats (because for every 2 cups of sugar, there are 3 cups of oats).
The number of cups of oats in the recipe is 3/2 (1.5) times the number of cups of sugar (because for every 3 cups of oats, there are 2 cups of sugar).
2x+3y=6
3y=-2x+6
3y/3=-2x+6/3
Y=-2/3x+2
