help please(ss below)

AZ:

Same thing as one of your previous questions, we need to solve for x The two angles add up to 180 3x + 18 + 4x + 15 = 180

crispyrat:

this is the same thing as before combine the x's then the numbers get rid of numbers divide by how many x's there are

AZ:

(It also says it at the bottom of your question lol) Can you add the like terms? What is 3x + 4x = ? What is 18 + 15 = ?

xXQuintonXx:

12x 33

AZ:

\( \color{red}{3x} + \color{orange}{18} + \color{red}{4x} + \color{orange}{15} = 180\) \( \color{red}{7x} + \color{orange}{33} = 180\)

AZ:

So do you see how we added the like terms? Now we want to get the 7x all by itself, so how do you move 33 to the other side?

crispyrat:

in other terms quinton how do you get make 7x+33=7x if you do that for one side then you do that for the other

xXQuintonXx:

u do the same thing to the other

xXQuintonXx:

so i subtract 7 on both sides?!?!?!?!?

xXQuintonXx:

cuz im lost rn

AZ:

no, the 7 has the 'x' with it we want to keep the 'x' on one side we want to move the other number to the other side

xXQuintonXx:

so i subtract 33 with 33

AZ:

no, it equals to 180 7x + 33 = 180 subtract 33 on both sides

Ashely:

u subtract 33 from 180 and 33 so you have 7x and whateverr 180-33 is

AZ:

Check again

xXQuintonXx:

i meant 147

AZ:

Good, and your last step is to just divide 7 on both sides

Ashely:

then u have 7x = 147 i think then i think u divide 147 by 7

xXQuintonXx:

21

xXQuintonXx:

x=21?
