oof nice

snowflake0531:

soooooooo you know that a straight line equals 180 degrees, right?

Katrin369:

Yeah

snowflake0531:

okay, so, do you know how you woudl write the equation then?

Katrin369:

I don't know. So sorry I can't think rn.

Katrin369:

I'm dumb

snowflake0531:

Okay, so, since you know that a straight line is 180 degrees, you can see that x, plus the other x, added with 76, equals 180 so, how would your equation look like *just put the words to symbols and numbers

Katrin369:

Ok so

snowflake0531:

lol, you can just write it here lol

Katrin369:

ok ya sorry lol

snowflake0531:

it would be x+x+76, which equals 180 degrees

snowflake0531:

so, your equation would be 2x+76=180 do you know how to find x?

Katrin369:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @snowflake0531 so, your equation would be 2x+76=180 do you know how to find x? \(\color{#0cbb34}{\text{End of Quote}}\) 76/2 = 38

snowflake0531:

ummm, no lol first, subtract 76 from each side what would your equation then look like?

Katrin369:

I'm confused

snowflake0531:

do you know how to solve for a variable in an equation?

Katrin369:

yes

snowflake0531:

so in 2x+76=180 what would you do first?

Katrin369:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @snowflake0531 so in 2x+76=180 what would you do first? \(\color{#0cbb34}{\text{End of Quote}}\) 180?

snowflake0531:

umm, wdym just by '180'?

Katrin369:

So, you have to subtract 2 from both sides of the equation to get the term with the variable by itself.

Katrin369:

Right?

snowflake0531:

no, but i need to gtg, it's pretty late in my time zone, my parents are going to be not-too-happy lol if @AZ can help... maybe lol
