I need help :) please if you know this I would appreciate it if you can help me

Step-by-step explanation:

2(3x) - 5x = 4

6x - 5x = 4

x = 4

B. -5(x-4)+8x=29

-5x+20+8x=29

3x+20=29

3x=9

x=3

C. 2y=18+2(3-y)

2y=18+6-2y

2y=24-2y

4y=24

y=6

D. c = -b - 11

3c + 6 = 6b

3( -b - 11) +6 = 6b

-3b-33+6=6b

-3b-27=6b

-27=9b

3=b

Find the measure of the exterior angle. *

MatroZZZ [7]

Step-by-step explanation:

✧ $\underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I \: O \: N}}} }:$

Set up an equation and solve for x :

⋆ $\large{ \bf{(4x + 9) \degree = 2x \degree + (3x - 12) \degree}}$ [ Exterior angle is always equal to the sum of two non - adjacent interior angles ]

~Remove the unnecessary brackets

⟶ $\large{ \bf{4x \degree + 9 \degree = 2x \degree + 3x \degree - 12 \degree}}$

~Add the like terms : 2x ° & 3x°

⟶ $\large{ \bf{4x \degree + 9 \degree = 5x \degree - 12 \degree}}$

~Move 4x to right hand side and change it's sign

~Similarly move 12 to left hand side and change it's sign

⟶ $\large{ \bf{9 \degree + 12 \degree = 5x \degree - 4x \degree}}$

⟶ $\large{ \bf{21 \degree = x \degree}}$

⟶ ${ \large{ \bf{x = 21 \degree}}}$

Now , Substituting the value of x in (4x+9)° [ Exterior angle ]

⤿ $\large{ \bf{4 \times 21 \degree + 9 \degree}} = \boxed{93 \degree}$

☥ $\boxed{ \boxed{ \large{ \tt{Our \: Final \: Answer : \boxed{ \underline { \tt{93\degree}}}}}}}$

Hope I helped ! ツ

Have a wonderful day / night ! ♡
