Solve 3/4x+1/4y=5 for y​
Sergeeva-Olga [200]

Answer:

y=3x+20

Step-by-step explanation:

So first, I don't like fractions so I would multiply the whole equation by 4. This will make the equation 3x+y=20. Then you have to isolate the y to find the answer so you should subtract 3x from both sides. This will make the equation look like this y=-3x+20. Therefore, y=3x+20

Y is the midpoint of Line xz .<br> if xz = 8x-2 and ya =2x+1 find x
faust18 [17]
Given that XZ = 8x - 2 and YZ = 2x + 1 and that Y is the midpoint of line XZ.

2YZ = XZ
2(2x + 1) = 8x - 2
4x + 2 = 8x - 2
8x - 4x = 2 + 2
4x = 4
