Twice the quantity of the sum of a number and three is equivalent to seven less than three times the number. Write an equation and find the number.

x = 13

Step-by-step explanation:

2( x + 3 ) = 3x - 7

2x + 6 = 3x - 7

2x = 3x - 7 - 6

2x = 3x - 13

2x - 3x = -13

-x = -13

=

x = 13

CHECK:

2( x + 3 ) = 3x - 7

2( 13 + 3 ) = 3( 13 ) - 7

2( 16 ) = 39 - 7

32 = 32

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

57 732
