(6 * y) +9
9y + 7
y -3 = 9 y = 9+3 y = 12
Answer: y= -1 Solution: 4 - 2 y = 7 y + 13 subtract 7 y from both sides: 4 - 2 y - 7 y = 7 y + 13 - 7 y 4 - 9 y = 13 subtract 4 form both sides: 4 - 4 - 9 y = 13 - 4 - 9 y = 9 now divide both sides by - 9: -9 y / - 9 = 9 /-9 y = -1
y - 4 = 9 y - 4 + 4 = 9 + 4 y = 13
(6 * y) +9
Oh, dude, that's like asking me to solve a math problem at a party. So, the expression "8 less than the product of y and 9" is just y times 9 minus 8. It's as simple as trying to find your friend's lost phone after a night out - a little annoying but not too complicated.
63 / 7 = 9. Therefore b = 9
xy = 20 x+y=9 x=9-y y(9-y) = 20 9y-y(squared) = 20 0= y(squared)-9y+20 0= (y-5)(y-4) y= 5 or 4, x= 5 or 4 The two numbers are 5 and 4.
9y + 7
that's impossibleAnswer:xy=9 and x+y=12reduces to the quadratic equation x2-12x+9=0so that once solvedx=-11.196 and y=-0.80385 (approx)
y - 9
y=x+9 y'=1 x+9=0 x=-9 y=-9+9 y=0
The sum of x and y decreased by their product is (x + y)- xy.
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
y
3x-y=9 y=3x-9
