Answer:

x > \frac{18}{5}

Step-by-step explanation:

5x + 2 > 20 ( subtract 2 from both sides )

5x > 18 ( divide both sides by 5 )

x > \frac{18}{5} or x > 3.6

Solve the following system of equations:
Vladimir79 [104]

Answer:

<u><em>(-1,1)</em></u>

Step-by-step explanation:

We can solve this by either graphing and finding ther point the lines intersect, or mathematically,  I'll do both.

<u>Graphing:</u>

<u>Mathematically:</u>

−2x + 4y = 6

y = 2x + 3

See the attached graph.  The lines intersect at (-1,1)

--------------------

I'll rearrange the first equation (to make it easier for me):

−2x + 4y = 6

4y = 2x + 6

y = (1/2)x + 1.5

Now lets substitute the second equation into the first so that we can eliminate y:

y = 2x + 3

[(1/2)x + 1.5] = 2x + 3

- (3/2)x = (3/2)

x = -1

If x = -1:

y = 2(-1) + 3

y = 1

The solution is x = -1 and y = 1, or (-1,1)

=================

Both approaches give us (-1,1), the solution to the system of equations.  It is the only point that satisfies both equations.
