Answer:
i hope this helps
Step-by-step explanation:
The equation would be (x+4)+x=18. X stands for the amount of pears Wilma bought, and (x+4) is the amount of pears Tania bought (because she bought four more pounds than Wilma).
(X+4)+x=18
2x+4=18 (now you subtract four from both sides)
2x=14 (to get x by itself, divide both sides by 2)
X=7
Wilma bought 7 pounds of pears :3
Answer:
Option A is the right answer.
146-4b = 122-1b
Reason: vertical angles
Step-by-step explanation:
substitute for y
x+3+4 = -6x
x+ 7 = -6x
7 = -7x
-1 = x
y = -1+3
y = 2
