VMariaS [17]3 years ago
4 0

Answer: x=6, y=4

Step-by-step explanation:

substitute y with (x-2)  in the 1st equation

10x-9(x-2)=24

10x-9x+18=24

x+18=24

x=6

Then use 6 for x to solve for y

y=6-2

y=4

I need help with this homework assignment, NO, I am not looking for answers, just help. Here it is.
shusha [124]
Surprisingly, a one-step equation <em>is </em>that simple; it's just an equation that takes one step to solve. So yes, 3 + 4 = 7 would be one you could do. You could also do a simple multiplication or division problem if you'd like, for instance you could do 4*3=12, or 12/4=3. Hope I helped!
