Answer:x=−136
Step-by-step explanation: Step 1: Simplify both sides of the equation.
2+x=

x+−15
x+2=

x−15
Step 2: Subtract 7/8x from both sides.
x+2−

x)=(8)*(−17)
Answer:
The second set.
Step-by-step explanation:
Consider the first set of ordered pairs.
For an increase of 9 is the x-values the y values increases by 1.
In the case of the second set the increase in y values compared with increase in y values is different:
x = 2-0 = 2, y = 10- 0 = 10. That is 5 units of y for every unit of x.
x = 5-2 = 3, y = 13-10 = 3. That is 1 unit of y for every 1 unit of x.
