Solve for x.
(9x – 16)+(3x + 11)+(7x – 5)=180

10

Step-by-step explanation:

See the picture attached.

x = 10

Step-by-step explanation:

Okay so the equation looks like this: (9x – 16)+(3x + 11)+(7x – 5)=180, this equation is really long at the moment so were going to simplify by adding the x variables and the whole numbers together:

9x + 3x + 7x = 19x

-16 + 11 + (-5) = -10

the equation once simplified will look like this:

19x + (-10) = 180

Now were going to add 10 to -10 and 180 in order to get rid of the -10 in the equation:

19x + (-10) = 180

         +10     +10

which would make the equation look like this:

19x = 190

now in order to segregate x from 19 we are going to have to divide 19 from 19x and 190:

19x/19 = 190/19

and when we do we get:

x = 10

Now to check it:

(9(10) – 16)+(3(10) + 11)+(7(10) – 5)

(90 - 16) + (30 + 11) + (70 - 5)

74 + 41 + 65 = 180
