Question 1010122
.
How many solutions are there in the following systems of equations? 
1. y=5x+3
y=9+x
--------------------------------------------------------

<pre>
Since the left sides of these equations are identical, the right sides are equal. 

It gives an equation

5x + 3 = 9 + x.

Simplify and solve it:

5x - x = 9 - 3,

4x = 6,

x = {{{6/4}}} = {{{1}}}{{{2/4}}} = {{{1}}}{{{1/2}}}.

The solution is unique.

There is only one solution.

There are no more solutions.
