Answer:

(-2,3)

Step-by-step explanation:

Doing it the way you did and working out the problem you substituted 3 into, x+3(3)=7, 3(3) is 9 and then you subtract 9 from both sides.

7-9=-2

x=-2

Then all you have to do is put it into ordered pairs.

(x,y)

(-2,3)

erastova [34]

Answer:

<em>(1/6)(-10x - 4) = -4 </em>

Step-by-step explanation:

(1/6)(-3x - 24) = -4

=> -3x - 24 = -4 x 6

=> -3x - 24 = -24

=> -3x = 24 - 24

=> -3x = 0

=> x = 0 (not 2) => Incorrect option

(1/6)(-5x - 8) = -4

=> -5x - 8 = -4 x 6

=> -5x - 8 = -24

=> -5x = 8 - 24

=> -5x = -16

=> x = 16/5 (not 2) => Incorrect option

(1/6)(-10x - 4) = -4

=> -10x - 4 = -4 x 6

=> -10x - 4 = -24

=> -10x = 4 - 24

=> -10x = -20

=> x = 2 => Correct option

(1/6)(-12x - 16) = -4

=> -12x - 16 = -4 x 6

=> -12x - 16 = -24

=> -12x = 16 - 24

=> -12x = 8

=> x = -3/4 (not 2) => Incorrect option

=> Option C is correct

Hope this helps!

Solve for g.
Montano1993 [528]
G = 16 or -16

|g| needs to be 16 because 15 + 1 is 16 and an absolute value is how far a value is from 0, so both |16| and |-16| are 16
