Answer:
On the first equation, which is (c-d)/5 - 2 = 0 Let's start by solving c.
First, you need to add 1/5d to both sides:
1/5 c + -1/5 d - 2 + 1/5 d = 0 + 1/5 d
1/5 c - 2 = 1/5 d
Next, add 2 to both sides:
1/5 c - 2 + 2 = 1/5 d + 2
1/5 c = 1/5 d + 2
Now, divide both sides by 1/5:
1/5 c/ 1/5 = 1/5 d + 2/ 1/5
c = d + 10
so, therefore, your answer is c = d + 10

Now we are going to do the 2nd equation, which is c-6d=0 Lets solve c.
The only thing you need to do is you need to add 6d to both sides:
c − 6d + 6d = 0 + 6d
c = 6d
So, therefore, your answer is c = 6d
Answer:
y=x +4
Step-by-step explanation:
A t-shirt costs $12 per t-shirt plus $3 shipping. Write the equation that describes the total cost c for the number of t-shirts purchase t.
so equation
c = 3 + 12t
if t = 1 then c(cost) = 3 + 12(1) = 3 + 12 = 15
if t = 2 then c(cost) = 3 + 12(2) = 3 + 24 = 27
if t = 3 then c(cost) = 3 + 12(3) = 3 + 36 = 39
if t = 4 then c(cost) = 3 + 12(4) = 3 + 48 = 51
