Solve for x
12x + 7x = 5x - 42

x = - 3

Step-by-step explanation:

Given

12x + 7x = 5x - 42, that is

19x = 5x - 42 ( subtract 5x from both sides )

14x = - 42 ( divide both sides by 14 )

x = - 3

X= -21/2, Please vote Brainliest.

Step-by-step explanation:

9x=5x-42

9x-5x=5x-42-5x

4x=-42

4x/4= -42/4

X= -21/2

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
