Question

plz help

solve for x = x – 3 > –9

Answer 1

x-3 >-9
add 3 to both sides
x-3+3 >-9+3
^cancels
x >-9+3

What is -9+3?

Answer 2

-6

Answer 3

correct @zahabaha

x >-6

understand?

Answer 4

not really

Answer 5

. –2x + 1 ≤ –11
how wuld u do thtis

Answer 6

Okay, I'll go step by step with another example.

x+5 > 10

So, you want to get the x alone (that is what solve for x means)
To get rid of the 5, you have to do the opposite.
The opposite of adding is subtracting.

So

x+5-5 is going to cancel the 5s and get the x alone and what you do to one side you do to the other sides.

x+5-5 > 10-5
x >10-5
x> 5

Answer 7

ooh now i gwt it

Answer 8

note when you times or divide by a negative number, remember to switch the side > <

Answer 9

but the question i asked looks harder

Answer 10

For -2x + 1 <= -11

First step: subtract 1 from both sides.
-2x +1 -1 <= -11 -1
-2x <= -12
x => 6

Answer 11

ohhk now i geety it thanks

Answer 12

The second step was to divide both sides by -2
which switches the sign.

Answer 13

wwat dont get tat part so it be's x<6

Answer 14

when you divide by a negative number (to get the x alone) you have to switch the sign.


examples:

-3x > 6
-3x/-3 > 6/-3
x < -2

-5x < -10
-5x/-5 < -10/-5
x > 2

Answer 15

ok so the sign becomes faceing x =< 6

Answer 16

\[x \ge 6\]

Answer 17

oh ok thanks
