Ok so first we find the equation that equals one variable.
2y = -x + 9
3x - 6y = -15
We solve for y.
2y = -x + 9
y = -x/2 + 9/2
Then we plug in this y value into the other equation to keep only one variable so we can solve for it.
3x - 6y = -15
3(-x + 9/2) - 6y = -15
-3x + 27/2 - 6y = -15
-9y + 27/2 = -15
-9y = 3/2
-y = 3/18
y = -3/18
Then we plug in this numerical y-value into the first equation which we found out by solving an equation for y.
y = -x/2 + 9/2
-3/18 = -x/2 + 9/2
-84/18 = -x/2
-x = 9 1/3
x = -28/3
Your answer would be (-28/3, -3/18)
Hope this helps!
Answer:
3
Step-by-step explanation:
x = 1
y = 1
6+4-7 = 3
Answer:
4 batches
Step-by-step explanation:
Total syrup made by Tamita = 18.5 ounces
Amount of ounces per batch = 4 ounces
If 1 batch = 4 ounces
x batches = 18.5 ounces
Cross multiply
4 * x = 18.5
x = 18.5/4
x = 4.625
Hence she can only make 4 batches of syrup
