Answer:

Step-by-step explanation:
The first thing that would need to be done is solving for y. This problem has already done this. The next step is to exchange y for 
That is all. This would mean that the function notation for the equation would be: 
Answer:
<h2>x = -0.5</h2>
Step-by-step explanation:

Step-by-step explanation:
3(x+2)-(2x-1)=4(3-x)
3x+6-2x+1=12-4x
3x-2x+4x=12-6-1
5x=5
x=1
Answer:
y = 17.5
Step-by-step explanation:
Use the direct proportion equation, y = kx
Plug in the x and y values to solve for k
y = kx
35 = k(140)
0.25 = k
Then, plug in the k value and given x value into the equation, and solve for y
y = kx
y = 0.25(70)
y = 17.5
