"20% off regular price" can be calculated by multiplying the regular price by (1.00-0.20), or 0.80. Thus, the discounted price will be 0.80($120), or $96.
Ok so if a system has no solutions, that means that no value will make it true
infinite solutions means that all numbers wil make the system true
example of no solution
a simplification that gives you
3=0
that is false so no solution
example of infinite
if after simplify you get
x=x
you can put all numer for x and get right answer
the simplified form of an equation with no solution will be in the form a=b where a is not equal to b, basically it gives you an obviously false statement like 3=4
simplified form on an equation with infinity solutions would end up with variable=variable or x=x or y=y

Answer:
1. x = 2.6
2. 7x + 1
Step-by-step explanation:
1.
Given:
4.75x = 12.35
Find x
4.75x = 12.35
Divide both sides by the coefficient of x, that is 4.75
4.75x / 4.75 = 12.35 / 4.75
x = 2.6
Check
4.75x = 12.35
4.75(2.6) = 12.35
12.35 = 12.35
2.
Given:
3x + 2 + 4x - 1
Combine like terms
3x + 4x + 2 - 1
7x + 1
