Solve the inequality

2x + 9 < 4x + 3

x > 3

Step-by-step explanation:

2x+9<4x+3

or, 9-3<4x-2x

or, 6<2x

or, (6/2)<x

or, 3<x

or, x >3

x>3

Step-by-step explanation:

2x+9<4x+3

2x-4x<3-9  (collect the like terms first)

-2x<-6    (divide both sides by -2 to get the value of x)

 ( the < sign changes because both sides are divided by -2)

x>3.

{x:x>3}= {x=4,5,6,7...}

       Check

2x+9<4x+3

2(4)+9<4(4)+3

8+9<16+3

17<19

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
