Multiply the first equation by 4 (so that both equations will have 8x terms) and then subtract:
8x-20y = -24
8x +3y = 68
------------
0 -23y = -92
Now divide both sides by -23:
y = 4
Find x by plugging y=4 into either equation:
8x +3(4) = 68
8x = 68 - 12
8x = 56
x = 7
So the answer is ordered pair is (7,4)
Answer:
16
Step-by-step explanation:
4*4
"Undefined" slope means the line on the graph is vertical, and that
tells the whole story right there. The 'x' coordinate is the same for
every point on the line. If (6, -1) is a point on the line, then you know
that the x-value of EVERY point on it is 6 .
It's a vertical line that intersects the x-axis at x=6, and the equation
of the line is x=6 .
The answer the this problem can be either 6/15 or 2/5
