Answer:
x = 15
Step-by-step explanation:
These angles are supplementary so you'd set up an equation like 3x -15 +150 = 180 then solve for x from there.
You multiply fractions simply by multiplying numerators and denominators with each other:

Answer:
x = −6
Step-by-step explanation:
I like to start off by simplifying the equation! Then, I use inverse operations to narrow it down until I reach the answer!
5x + 12= −18
5x + 12 <u>− 12</u>= −18 <u>− 12
</u>
5x = −30
5x<u>/5</u> = -30<u>/5</u>
<u>x = -6</u>
