Umm well ill show you how I do it so if it is 67 minus 72 I would subtract the tens spot first then I would do the ones it works for me and it is easy so I hope this helped ohand the answer is -5
B!
The equation x-4y= -4 is the graph, right? So that means when x is, lets say, 2, then:
2-4y= -4
Simplify
-4y=-6
y=3/2
Now if you think about it, if you plug in any number for x and get some value of y, that is the point on the graph at that x value.
Hope this helps!
The answer is 5 and 18. This is because 5 times five is 25. 25 minus 7 is 18.
3x=129 , x =43 distribute 3 to get x by itself
