Question

-2 (x + 3) < 10

Answer 1

open the brackets!!

Answer 2

\[-2 (x + 3) < 10\]\[-2 x - 6 < 10\]\[-2 x < 16\]\[x> -8\]The sign flips because you divide by a negative.

Answer 3

I need help!! I done 3* (6 -5 * X) < 20 -X*
move 6 to the right of expression it becomes 3* ( 3* 3 *( -5*x + 6 ) < 20 – x *
Look at 3* ( -5* x + 6 < 20 – x *
Moved 20 to the right of expression
It becomes 3 * ( - 5 * x + 6 ) < - x + 20 *

Look at 3*( -5*x + 6) < - x + 20
Expanded term 3 by using associated property on (-5 *x + 6)
It becomes -3 *5 *x + 3*6 < -x + 20

Look at -3 *5 *x + 3 *6 < - x + 20
Multiplied numerator integers
It becomes -15* x + 18 < -x +20

Look at -15 * x + 18 < -x + 20
Multiplied numerator integers
It becomes -15* x + 18 < -x + 20
is this right?
