Any multiple of (-2x+3y=18) would constitute an "other equation" forming a system with an infiinite number of solutions. The reason for that is that the two equations would be "dependent."
On the other hand, looking at the system
<span>-2x+ 3y= 18
</span><span>-2x+ 3y= 19
we see that there is no solution. Why? Because -2x + 3y cannot equal 18 and 19 at the same time. You'd have two non-intersecting, parallel lines.

Answer:
10
Step-by-step explanation:
3x + 5y
Let x= -5 and y =5
3(-5) + 5(5)
Multiply first
-15 +25
Then add

Answer:
<em>125</em>
Step-by-step explanation:
Use your Equation: <em>A= B*H (base x height)</em>
<em>7.8(16)= 124.8</em>
Rounded to the nearest whole number<em>: 125</em>
Solve for x by simplifying both sides of the equation then isolate the variable your answer is x=10.
