let's solve this problem:-the first step; (find the 'y')8y-7 = 23 -2y8y+2y = 23+710y = 30y = 30:10y = 3-the second step; (change the 'y' with '3')8(3) -7 = 23 -2(3)24 -7 = 23 -617 = 17well, The conclusion and the answer is;8y -7 = 23 - 2y --> is True Equal ;)
x - 2y = 04x - 3y = 15From the first equation, x = 2y.SUBSTITUTING this value of x in the second equation,4*(2y) - 3y = 15 ie 8y - 3y = 15 or 5y = 15 so that y = 3and then, x = 2y gives x = 2*3 = 6Answer: x = 6, y = 3
5x - 4y ≥ -203x - 2y ≤ -8y ≥ -3
First, solve for y:4x + 8y = 24∴ x + 2y = 6∴2y = 6 - x∴ y = 3 - x/2Let y = 0:0 = 3 - x/2∴ x / 2 = 3∴ x = 6So the y-intercept occurs at the point (6, 0)
4x-2y = 6 -7x+2y = -15 Add both equations together in order to eliminate y: -3x = -9 Divide both sides by -3 in order to find the value of x: x = 3 Substitute the value of x into the original equations to find the value of y: Solution: x = 3 and y = 3
y equals 3
If: 8y-2 = 3-2y Then: 8y+2y = 3+2 So: 10y = 5 Therefore: y = 5/10 or as a 1/2 in its simplest form
let's solve this problem:-the first step; (find the 'y')8y-7 = 23 -2y8y+2y = 23+710y = 30y = 30:10y = 3-the second step; (change the 'y' with '3')8(3) -7 = 23 -2(3)24 -7 = 23 -617 = 17well, The conclusion and the answer is;8y -7 = 23 - 2y --> is True Equal ;)
4(2y + 3)
Not sure which you mean, take your pick: (8y)3+27=(8y+3)((8y)2-3*(8y)+9)=(8y+3)(64y2-24y+9); or 8y3+27=(2y+3)(4y2-6y+9)
eq. 1 is x-2y=0 which means x=2y eq. 2 is 4x-3y=15 subst. x=2y in eq. 2 4(2y)-3y=15 8y-3y=15 5y=15 y=3 subst. y=3 in eq. 1 we get x=2(3) x=6 Ans: x=6 and y=3 is the required solution. Thank you.

2y = 6x - 8y = 3x - 4========m(slope) = 3=========

If that's + 2y, the answer is (y + 4)(y - 2)
It is like saying, "How much is 8 yams plus 2 yams plus 3 yams?" Add the numbers: 8+2+3 = 13. The answer is the number of yams. 8y+2y+3y = (8+2+3)y = 13y.
The solution to 2y^3 - 16y^2 + 24y is factored as 2y(y^2 - 8y + 12), which further simplifies to 2y(y - 2)(y - 6).
