-5x + 2 greater than or equal to 22. How would you solve this?

Answer 1

-5x+2=22
subtracting 2 from both sides
-5x=20
dividing both sides by-5
x=20/-5
x=-4
-5x+2>22
subtracting 2 from both sides
-5x>20
dividing both sides by-5 (according to the rules in inequalities the sign changes when we divide/multiply by a negative no.)
x<20/-5
x<-4
from above 2 eqs. we get x=-4 or x<-4
from both we can conclude that x can be any real no. less than -4

Answer 2

-5x + 2 >= 22
-5x >= 20
-x >= 4
x <= -4

x is less than or equal to -4. Substitute any value less than -4 (-5, -6 , -100 ect) or put x = -4 and check. The condition is satisfied in all these cases.

While making -x into x, The >/< operation must change.

Answer 3

-5x + 2 > or = 22

- 5x > or = 22 - 2 = 20

x < or = - 20/5 (Note the reversal of the < sign to <)

x < or = - 4

Answer 4

-5x + 2 >= 22

Take 22 across to the right and take -5x across to the left, changing both their signs.

-22 + 2 >= 5x
-20 >= 5x

Divide both sides by 5.

-4 >= x

Therefore, x <= -4

Answer 5

Subtract 2 from both sides of the equation first so you get -5x is greater than/ equal to 20. Then divide both sides of the equation by -5 and switch the greater than/equals to sign around, so you get x is less than/ equal to -4. [I think]

Answer 6

-5x + 2 >or= 22

-5x + 2 - 2 >or= 22 - 2

-5x >or= 20

-5x + 5x >or= 20 + 5x

0 >or= 20 + 5x

0 - 20 >or= 20 + 5x - 20

-20 >or= 5x

-20 / 5 >or= 5x / 5

-4 >or= x

x
Answer: x is any number less than or equal to -4

Answer 7

-5x + 2 >= 22

subtract 2 from each side

-5x >= 20

divide both sides by -5. when you divide by a negative number, it causes the greater than/less than sign to flip.

x <= -4

Answer 8

-5x + 2 ≥ 22
- 20 ≥ 5x
x ≤ - 4

Answer 9

well i m not sure but it can be like this
-5x+2
-5*-6+2= 30+2 = 32 >22

Answer 10

There's no way you could pinpoint X - it is any number higher than 4.

5 x 4 + 2 = 22
