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
To simplify 216, we need to find its prime factors. 216 can be expressed as 2^3 * 3^3. To simplify further, we can combine the factors to get 2 * 2 * 2 * 3 * 3 * 3, which equals 6 * 6 * 6 or 6^3. Therefore, 216 simplified is 6^3.
-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.
