Step-by step explanation:
That's a great question. Look for things such as these:
x=x (infinite solution)
x=12 (one solution)
x+3 = x + 5 (no solutions)

Answer:
Both D and E are true statements.
Step-by-step explanation:
When you have the base form of slope-intercept form:
y = mx + b
The m (which is the coefficient of x) is the slope of the line. In this case that would be 4.
The b is the intercept. In this case it would be -6
Answer:
54
Step-by-step explanation:
all you have to do is times 18 by 3
The complete question is
Susan and Steven are cousins. The sum of their ages is 33. The difference between three times Steven's age and half of Susan's age is 36. Find <span>the age of Susan and Steven
let
x-----> </span>Susan's age
y----> Steven's age
we know that
y+x=33-----> equation 1
3y-x/2=36----> multiply by 2----> 6y-x=72----> equation 2
adds equation 1 and equation 2
y+x=33
6y-x=72
-------------+
7y=105--------> y=15
x=33-y----> x=33-15----> x=18
the answer is
Susan's age is 18
Steven's age is 15
