stiv31 [10]

Answer:

8.33333333333

Step-by-step explanation:

Solution for 3x-7=18 equation:

3x - 7 = 18

3x = 18 + 7

3x = 25 (divide both sides by 3 to get x)

3x/3 = 25/3

D.) It is not correct because the second number tells you how far to go up or down, not across.

Second number represents y-coordinates, so they are the points in vertical direction, in that case you can't move in x-axis which is horizontal.

Hope this helps!
