<span>The sum of two numbers is 50. The smaller number is 18 less than the larger number. What are the numbers?
-----
Equations:
x + y = 50
x = y - 18
-------------------
Add and solve for "x"::
2x = 32
x = 16
-----
Solve for "y"::
16 + y = 50
y = 34
-----------------
Hope I helped!

After you re-arrange the equation, you'll find out that you got y=3x+6....okay, this equation is a linear equation, you can use y=mx+b {where m=3, and b=6}. then to find the co-ordinate of (x,y) which is the point, substitute 1,2,3,4.... for x in 'y=3x+6' to figure out the co-ordinate of y.
answer: (1,14), (2,16), (3,19), (4,22)
120 + 0.40m = 50 + 0.50m
120 - 50 = 0.50m - 0.40m
70 = 0.10m
70/0.10 = m
700 = m....they will be the same at 700 miles
No because y=5 is a horizontal line on a graph, in this scenario the x-values would stay the same
