This is true since the first life forms evolved from bacteria that lived in water and also no living being on this earth can survive without water
Let t represent "total price." Then 0.20t = $1600, and t = $1600/0.20 =
$8000 (answer)
You find three times that number.
Isolate the x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS (Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction)
First, subtract 6 from both sides
-4x + 6 (-6) = -38 (-6)
-4x = -38 - 6
-4x = -44
Next, fully isolate the x by dividing -4 from both sides
(-4x)/-4 = (-44)/-4
x = -44/-4
x = 11
11 is your answer for x.
