Question

Which value is NOT a solution of the inequality -2x + 5<7?

-3

5

7

1

HELP PLEASE

Answer 1

its 1, i think...

Explanation:

If they are asking which one would equal to -2x+5<7 just combine like terms by moving the 5 to the 7 and get 7-5=2. So -2x=2, then 2/-2 is -1. Basically the answer is x=-1. But it seems like thats not a choice...

Answer 2

Answer:1

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

-2*x+5-(7)<0

Pulling out like terms

1.1 Pull out like factors :

-2x - 2 = -2 • (x + 1)

:

2.1 Divide both sides by -2

Remember to flip the inequality sign:

Solve Basic Inequality :

2.2 Subtract 1 from both sides
