YALL HELP ME OUT (9x+4)+(7x−6)
(12x+5)+(3x−7) 7y+15−7y−8

use cymath or photo math it will help

1) 16x-2

2) 15x-2

3)     7

Step-by-step explanation:

1) (9x+4)+(7x−6)

    9x+4+7x-6

    9x+7x+4-6

    16x+4-6

      16x-2

2) (12x+5)+(3x−7)

    12x+5+3x-7

    12x+3x+5-7

     15x+5-7

       15x-2

3) 7y+15-7y-8

   7y-7y+15-8

       15-8

          7

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
