3x^2 + 5x - 8 = 0 + 8 + 8 3x^2 + 5x = 0 8x ^2 = 0
5x + 8 = -3x + 16 add 3x to both sides, this gives you... 8x + 8 = 16 minus 8 from both sides, this gives you... 8x = 8 divide by 8 to get what x equals (must divide both sides), this gives you... x = 1
When x equals 8, the value of 5x would be 5 times 8, which is 40.
32-5x=3x+8 32-5x-8=3x+8-8 24-5x=3x 24-5x+5x=3x+5x 24=8x x=24/8=3
That depends on the plus or minus values 0f 8, 5x and 7 which have not been given
-2, 1.74 and 0.46
20x2 - 27x -8 20 * -8 is -160, and -32 and 5 add to -27 20x2 - 32x + 5x - 8 4x(5x-8) + 1(5x-8) (4x + 1)(5x-8)
3x^2 + 5x - 8 = 0 + 8 + 8 3x^2 + 5x = 0 8x ^2 = 0
5x + 8 = -3x + 16 add 3x to both sides, this gives you... 8x + 8 = 16 minus 8 from both sides, this gives you... 8x = 8 divide by 8 to get what x equals (must divide both sides), this gives you... x = 1
if it is 5x + 8 = 23 then the answer is 3. if it is 5x - 8 = 23 then the answer is 31/5.
When x equals 8, the value of 5x would be 5 times 8, which is 40.
7x-5x=8 2x=8 x=4
32-5x=3x+8 32-5x-8=3x+8-8 24-5x=3x 24-5x+5x=3x+5x 24=8x x=24/8=3
The equation x2 - 5x - 24 = 0 has the two solutions 8 and -3 for x.
5x-4y=8
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
-6 - (-8) = 2
