If y=x and y=x+2 are the same, then how many solutions does it have
Answers
Answer:
none
Step-by-step explanation:
"they are the same" translates to ...
x = x +2
0 = 2 . . . . . . subtract x from both sides. — a FALSE statement
There are no values of x or y that make this true.
_____
The two equations describe parallel lines, so they cannot be "the same." There are no points of intersection.

so they are
n,n+2,n+4
their sum is 78
n+n+2+n+4=78
3n+6=78
minus 6
3n=72
divide 3
n=24
smallest is 24
3x = 75

y - pencil
6x + 5y = 2.50
3x + 2y = 1.15
Thus, 3x = 1.15 - 2y
Therefore, 6x = 2.30 - 4y
Substituting the value of 6x ;
(2.30 - 4y) + 5y = 2.50
or, 2.30 + y = 2.50
=> y = 0.20.
Substituting the value of y ;
6x = 2.30 - 4(0.20)
6x = 2.30 - 0.80 = 1.5
6x = 1.5
=> x = 0.25
Thus, 1 pen costs 0.25 $ and 1 pencil costs 0.20$.
Thus, cost of one pen is 0.25$.
Cost of 4 pencils is 0.80 $
0.25$ + 0.80$ = 1.05$
