Answer:
x = 9
this is a ratio problem. You can see that 12/6 = 2, so you can also take 18/2 to get 9.
Y = 7x + b
2 = 7 + b, b = -5
Y = 7x - 5
Answer:
No solutions
Step-by-step explanation:
Rewrite x-2y=4 x-2y=5 in column form:
x-2y=4
x-2y=5
Because both equations have x - 2y on the left and different constants on the right, we know immediately that there is no solution. These two lines are parallel and different; they never cross.
