Y=2x-4
X+2y=10
Put y into the x equation
X+2(2x-4) =10
Expand and simplify
X+4x-8=10
5x-8 =10
5x=10+8
5x=18
X=18/5
Insert x into the original equation to get y
Y=2x-4
Y=2(18/5)-4
Y=16/5

Answer:
pounds
Step-by-step explanation:
The customer will be charged extra if the weight of their suitcase is above 48 pounds.
Let the weight of the suitcase = w (in pounds)
Therefore, w above (greater than) 48 pounds is written mathematically as:
pounds
This is the inequality that represents w, the weight of the suitcase in pounds, that will have an extra charge.
