Answer:
One solution
Step-by-step explanation:
5x-8 = 3x+8
2x = 16
x = 8 = true once
Answer:
infinitely many solutions
Step-by-step explanation:
I assume that you meant
3x = -12y + 15 and x + 4y =5 (you accidentally omitted the 'y')
Multiplying the second equation by 3 yields
3x + 12y = 15
... which is identical to the first equation. Thus, the two lines coincide, and we conclude that there are infinitely many solutions.
Answer:
5)
8, 6, 4, 2= 67°
5,7,1,3= 113°
6) not sure about this one!
When you subtract an integer from an integer you add it Ex: -30-40=-70
