Question

I also need help on this one too

Answer 1

Answer: x=38

Explanation:

(4x-9)=(3x+29)

4x-9=3x+29

combine like terms: subtract 3x from both sides

x-9=29

combine like terms: add 9 to both sides

x=38

Check answer:

4*38=152

152-9=143

3*38=114

114+29=143

Answer 2

4x-9= 3x+29

+9 +9

4x=3x+38

-3x -3x

x=38

Now that we have x we can substitute it into one of the equations

3(38)+29=

114+29=

143 <- this is the angle
