Step-by-step ex6757lanation:
- Using
substitution
means you are going to solve one equation for one variable and substitute with
its value in the other equation in order to get also an equation with one
variable.
Answer:
(0,5), (2,4), (4,3), (6,2), (8,1), (10,0), (12,-1), (14,-2), (16,-3), (18,-4), and (20,-5)
Step-by-step explanation:
The given linear equation is :

Or

Any ordered pair that satisfies this equation is a solution.
When x=0,

(0,5) is a solution
When x=2,

(2,4) is a solution.
When x=4,

(4,3) is a solution;
When x=6:

(6,2).
When x=8,

Another solution is (8,1)
When x=10,

(5,0) is a solution
When x=12,

(12,-1) is a solution.
When x=14,

When x=16, we get:

When x=18, we get:

Where is the questions at
So, Bob needs 2 cups of concentrate (I'll use the variable c to shorten it) for every 3.5 cups of water (w). When he has 6 cups of c, he has three times the original recipe, and therefore we need 3w as well.
3.5x2=6+1=7. So we need 7 cups of water.
Now, 6 cups of concentrate + 7 cups of water = 13 cups of orange juice.
Bob can make 13 cups of orange juice.
Hope I helped!
