I believe the converse is: if 2x equals 6 then x equals 3 inverse: if x doesn't equal 3 then 2x doesn't equal 6 contrapositive: if 2x doesn't equal 6 then x doesn't equal 3
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
6 2(6) + 3 = 9
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.

By ignoring the whole numbers. 1 and 6/8 = 1 and 3/4
2
They are: 2*3 = 6
divide both numbers (if even, as in your case) by 2. It equals 3/15. Since you can continue, divide again, but this time, they are both divisible by 3, so divide by 3. It equals 1/5. Since you can no longer divide evenly, 6/30 simplified is 1/5. or, a faster way is divide 6/30 by 6. It still equals 1/5.
Divide both numbers by their GCF, which is 3. The answer is 2/19
2x = 6 divide both sides by 2 2x/2 = 6/2 simplify x = 3
Oh, dude, like, 216 simplified is 216. You know, because sometimes math just wants to keep things simple and not mess around with all that reducing and simplifying nonsense. So yeah, 216 is its own simplified, carefree self.
-6x/-6=18/-6 x=-3
Both numbers will divide exactly by 6 - therefore, 6/6=1, and 18/6=3. This simplifies 6/18 to 1/3
x+6/2 = 9/5 Start x+3 = 9/5 Simplify 6/2 into 3 x + 3 = 1.8 Simplify 9/5 into 1.8 x = 1.2 Subtract 1.8 from 3 (or x = 6/5)
Well - 6/18 simplified is 1/3. This is because 6 & 18 will both divide exactly by 6. To simplify a fraction, you're trying to find the lowest equivalent numbers for the numerator and denominator.
