-7x + 4y = -6
2x - 5y= 21
<u>Make it so x's are equal</u>
-14x + 8y = -12
-14x - 40y = 147
<u>Subtract</u>
-32y = -169
<u>Divide</u>
y = 5.28125
<u>Plug in the y value</u>
2x - 5(5.28125) = 21
<u>Simplify</u>
2x -26.40625 = 21
<u>Add</u>
2x = 47.40625
<u>Divide</u>
x = 23.703125
Hope this helps! ;)
Answer:
2 cups of sugar to 6 cups of water
Step-by-step explanation:
3 cups of sugar to 9 cups of water is our starting point.
If we plan to use only 2 cups of sugar, which is 2/3 of 3 cups,
multiply both quantities in "3 cups of sugar to 9 cups of water" by 2/3:
(2/3)(3 cups of sugar) to (2/3)(9 cups of water), obtaining:
2 cups of sugar to 6 cups of water.
Note that the ratio here is 3:9, which reduces to 1:3: 1 cup of sugar to 3 cups of water.
