Answer:
x=28
Step-by-step explanation:
-7(3+6x)=9(-5x+7)
-21-42x=-45x+63
-21-42x-(-45x)=63
-21-42x+45x=63
-21+3x=63
3x=63-(-21)
3x=63+21
3x=84
x=84/3
x=28
C i hope this helps getting all heads there is about a 0.1 chance and a 0.1 chance of getting all tails
these two bars | | mean <u>absolute value</u>
here's how to find x
| x - 7| = 2
first apply the absolute rule
x - 7 = 2 x - 7 = -2
in both equations add 7 on both sides
x - 7 + 7 = 2 + 7 x - 7 + 7 = -2 + 7
then simplify the expressions
x = 9 x = 5
now combine these two solutions to get your answer
x = 9 or x = 5
hopefully my explanation helps
