Another way to do it is
2x-y=17
x-y=10, x=10+y
substitute x=10+y for x in 2x-y=17 and get
2(10+y)-y=17
20+2y-y=17
20+y=17
subtract 20 from both sides
y=-3
subsitute y=-3 into equation x-y=10
x-(-3)=10
x+3=10
subtract 3 from both sides
x=7
or subsitute into 2x-y=17
2x-(-3)=17
2x+3=17
subtract 3 from both sides
2x=14
divide both sides by two
x=7
Answer:
Step-by-step explanation:
less than I think
Answer:
Yes
Step-by-step explanation:
The two rules for a proportional relationship are
- The line is straight (Check)
- The line goes though the origin (Check)
Because of that it is a proportional relationship.
Hope this helps :)
I am assuming you are multiplying the y as well. if so, it is -3*2*3 and that would be -18 so it would be true.
In point-slope form, the equation is :
Y-6=2(x+4)
Hope this helps✨❤️
