Well just do regular math to answer but if its looking for pattern u can tell that the consistent number is 7
The solution to a system of (linear) equations is the point where the graphs intersect. Consider two parallel lines. By definition, two parallel lines never intersect each other, but all pairs of non-parallel lines will eventually intersect. That means they will also have a solution.
Let's consider what makes a line parallel to another line. It basically looks identical, having the same steepness (slope), but the graph is just shifted over. That is, a parallel line would have the same slope and a different y-intercept. For our equation

, or

in slope-intercept form, a parallel line will be of the form

.
That describes the form of a parallel line, which we do not want. Any other line, however, will give a solution to our system, so we merely want a line where the slope does not equal 2.
We can have any equation of the form

.
False, 24 x 10 x 90 = 21,600, 90 x 2,400 = 216,000
Answer:
y = 6 so
2x + 3y = 36y is equal to:
2x + 3*6 = 36*6
-> 2x + 18 = 216
We must now move 18 to the other side of the equation. As we do that, we also change it's sign to negative 18:
2x = 216 - 18
We simplify this
2x = 198
Now, that we got to this point, we know that 2x is equal to 198. To find x we must divide the both sides of the equation by two:
2x/2 = 198/2
And we get that
x = 99
