Simplifying

7x + -4y = 23


Solving

7x + -4y = 23


Solving for variable 'x'.


Move all terms containing x to the left, all other terms to the right.


Add '4y' to each side of the equation.

7x + -4y + 4y = 23 + 4y


Combine like terms: -4y + 4y = 0

7x + 0 = 23 + 4y

7x = 23 + 4y


Divide each side by '7'.

x = 3.285714286 + 0.5714285714y


Simplifying

x = 3.285714286 + 0.5714285714y

What is the product of -8 1/3 and 3 2/5
fenix001 [56]
-28 1/3

To get this, first, transform the mixed numbers into improper fractions. To do this, multiply the denominator and the whole number then add to the numerator.

Once this is done, set up the equation of -25/3 x 17/5 and cross multiply - -25 and 17 then 3 and 5. Don't forget that the 25 is negative so the product of the numerators will be negative!

Once this is done, you'll have a larger negative improper fraction. You'll need to transform it into a mixed number. To do this, find how many times 15 goes into 425 (28). The remainder will be the fraction or 1/3. Make sure to simplify the fraction!

Hope this helps!
