Angle BAC is 75 because you subtract 27 from 102.
First step: multiply the 5(x3) and it will give you x15 or most commonly written as 15x. you should now have 15x-(-20).
Second step: since you cannot subtract -20 from 15x because it has a variable, the final answer is just 15x-(-20), or 15x+20.
<span>9-4(2x-1)=45
Multiply -4 by 2x and -1
9-8x+4=45
Subtract 9 from both sides
-8x+4=36
Subtract 4 from both sides
-8x=32
Divide both sides by -8
Final Answer: x= -4</span>
