Commutative property of addition is being used.

This means that you can switch around where the numbers are and still get the same answer.

Hope this helps!

if the farmers market sold 35% of it produce and has 280 peaches remaining, how many peaches did it originally have on hand.
jonny [76]

Divide the amount left by the percentage left:

they sold 35%, so there is 65% remaining.

280 / 0.65 = 430.769

Round to 431

Now check:

431 x 0.35 = 150.85

Round to 151

431 - 151 = 280 left.

They originally had 431 peaches.

What is the solution to the following system of linear equations?
OverLord2011 [107]
There are two ways to solve system of equations.

1) substitution method

2) elimination method

4x - y = -6

x - 2y = -5

For thus problem, i'll be using the substitute method.

So, using the equation x - 2y = -5:

Solve for "x" by adding 2y to both sides of the equation.

x = 2y - 5

Now we know what "x" is, we can substitute it in the other equation.

4x - y = -6

4(2y - 5) - y = -6

8y - 20 - y = -6

7y - 20 = -6

7y = 14

y = 2

We now know the numerical value of y. So, all we have to do is plug in y into either system of equation to solve for the numerical value of x.

4x - 2 = -6 x - 2y = -5

4x = -4 x - 2(2) = -5

x = -1 x - 4 = -5

x = -1



The solution is (-1, 2) where x equals -1 and y equals 2.
