Answer:
Step-by-step explanation:
90 times 3 = 270
9x-3 + 6x + 48 = 270
add like terms, 48-3 = 45
9x + 6x + 45 = 270
subtract 45 both sides and add like terms again
15x = 225
divide 15 on both sides
x = 15
y= -30
THis is because you substitue 3 for X and then multiply -10 and 3 and a negative times a positive is a negative so -10 times 3 is -30
The answer is " 1320000000 ft " away
