x = 6y = 89x + 10y = 9(6) + 10(8) = 54 + 80 = 134
Multiply the first by 8 and the second by 3
y=3.25 I believe that is the answer.......I have not math like that in a while.
y + x = 9 10y + 20x = 100 This is a basic linear system of equalities. We can start by rewriting the first equation as: -10y - 10x = -90 by multiplying the equation by -10, from here we can eliminate y and solve for x (-10y - 10x = -90) + (10y + 20x = 100) = (10x = 10) This yields x = 1, and by plugging x into the first equation y = 8
you have to bring the "y" to one side. 10y - 6 = 2 + 4y 10y-4y = 2 + 6 6y = 8 y = 8/6 If you substitute 8/6 into y you will find that 8/6 is the answer

You're there. 4x = 10y - 8.[so subtract 10y from both sides, 4x - 10y = -8]multiply b.s. by -1 , gives -4x +10y = 8
y + x = 9 10y + 20x = 100 This is a basic linear system of equalities. We can start by rewriting the first equation as: -10y - 10x = -90 by multiplying the equation by -10, from here we can eliminate y and solve for x (-10y - 10x = -90) + (10y + 20x = 100) = (10x = 10) This yields x = 1, and by plugging x into the first equation y = 8
(y - 8)(y - 2)
you have to bring the "y" to one side. 10y - 6 = 2 + 4y 10y-4y = 2 + 6 6y = 8 y = 8/6 If you substitute 8/6 into y you will find that 8/6 is the answer
If x = 8 and y = 10 then it is 44.
It is the property that equals plus equals are equals.
(y - 8)(y - 2)
x + 2y = -5 2x + 3x = -9 5x = -9 x + 2y = -5 x = -2y - 5 5(-2y - 5) = -9 -10y - 25 = -9 -10y = 16 y = -5/8 x = -2y - 5 x = -2(-5/8) - 5 x = -5/4 - 5 x = -25/4 (-25/4, -5/8)
it is 28
