the equations that will have only one solution are:
- 19x - 18 = -19x + 18 (option c)
- 19x + 18 = -19x + 18 (option d)
<h3>
When we have only one solution?</h3>
An equation of the form:
a*x + b = c*x + d
Has one solution only if a ≠ c.
With that in mind, we can see that the equations that will have only one solution are:
19x - 18 = -19x + 18 (option c)
19x + 18 = -19x + 18 (option d)
In the other two cases, the slopes of the linear equations are equal, so these equations have no solutions or infinite solutions.

Answer:
5x = 14
Step-by-step explanation:
If 5 yards of fabric is $14 you need an equation that would solve how much 1 yard of fabric costs. You can say 5x = 14 or x = 2.8 which means that one yard of fabric (1x or just x) is $2.80.
