Solve the inequality 2x + 8 &lt; 5x − 4.
Jobisdone [24]

The answer should be X>4

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :  

                    2*x+8-(5*x-4)<0  

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  -3x + 12  =   -3 • (x - 4)  

Equation at the end of step  1  :

Step  2  :

2.1    Divide both sides by  -3  

Remember to flip the inequality sign:  

Solve Basic Inequality :

2.2      Add  4  to both sides

            x > 4

Is – 7 a solution to the equation 8 {1/4x +3/4} -3 = 17
I am Lyosha [343]

Answer:

No

Step-by-step explanation:

Start by using the distributive property to simplify 8(1/4x+3/4):

8•1/4x=2x

8•3/4=6

The equation now reads: 2x+6-3=17. Subtract 3 from six and you get 2x+3=17.

You can now proceed to answer this like any two step linear equation.

2x+3=17

-3 -3

2x=14

x=7

7 is the solution to this equation
