Answer:
8
Step-by-step explanation:
77+50=127
180-127=53
7x-3=53
7x=53+3
7x=56
x=56/7
x=8
23,999
Un refrigerador de $8,500.50
Un televisor de $3,500.50
Una computadora de $6,900.00
Una lavadora de $4,999.00
8,500.50 + 3,500.50 + 6,999.00 + 4,999.00 = 23,999.00
Answer: 4
Set them equal to each other since they're both equal to y
3x-5=.5x +5
add 5 to both sides
3x=.5x+10
subtract .5x from both sides
2.5x=10
divide both sides by 2.5
x= 4
