Can somebody please solve this for me and show the work? it doesn't look too hard I'm just dumb.​
lana [24]

Answer:

x = 7

Step-by-step explanation:

  • vertical angles are pairs of opposite angles made by intersecting lines. and they are congruent

x + 16 = 4x - 5

x - 4x = - 5 - 16

- 3x = - 21

- x = - 21/3

- x = - 7

x = 7

hope it helps

and please just focus on your questions and use knowledge

When you subtract one negative integer from another, will your answer be greater than or less than the integer you started with?
SVEN [57.7K]
So say for example u have -7 - (-5), think of subtracting integers as adding the opposite, so ur adding the opposite of -5, the opposite of -5 is 5, so ur adding -7 and 5= -2
another one: -15 - (-18)
again, adding the opposite. -15 plus positive 18= 3
