If xy-2x=16, and y+4=-2, then x=?

y + 4 = -2

y = -4-2

y = -6

xy - 2x = 16

-6x - 2x = 16 (putting y = -6)

-8x = 16

8x = -16

x = -16/8

x = -2

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
