Solve for x: 2x - 3+ 4x = 27
answers
x=4
x=5
x=12
x=15

x=5

Step-by-step explanation:

2x-3+4x=27

6x-3=27

6x=27+3=30

x=30/6

x=5

correct answer:

b.(19,-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
