Answer:
Step-by-step explanation:
I think its the second one.
3y = 5x+30 , y+5x = 50
using elimination method ...
3y-5x=30
+ y+5x=50
——————
4y = 80
y= 20
so using one of the original equations..
20 + 5x = 50
5x = 30
x =6
x = 6
y = 20
Hi! Going from equation one, you should put your starting point at negative 10. Then make an over-arrow over to negative five showing where you added five. After this, make another arrow from negative five to seven. Then you’re done! Hope this helps!
