What is 8x - 4x 12?
If that's 8x - 4x = 12, it's an equation where x = 3
Which expressions are equivalent to 8x?
4x
8x-6y equals 18 and 4x-6y equals 6?
8x - 6y = 184x - 6y = 6from the first equation:6y = 8x - 18substitute this value in the second equation:4x - (8x - 18) = 64x - 8x + 18 = 6-4x = 6 - 18-4x = -12x = 3Solve for y :8 x 3 - 6y = 1824 - 6y = 186y = 6y = 1
What is x if 28 is 8x 12-7?
28=8x+12-7 28=8x+5 23=8x x=23/8
What is x squared plus x-2 squared equals x-4 squared?
-6
8x-1 equals -4x plus 23?
8x-1 = -4x+23 8x+4x = 23+1 12x = 24 x = 2
Solve 8x-1 equals 23-4x?
8x-1=23-4x 12x=24 x=2
How do you solve 8x - 1 equals -4x plus 23 algebraically?
If you're trying to find x: 8x-1=-4x+23 8x+4x=23+1 12x=24 x=24/12 x=2 wasn't really sure if that's what your question was but hope it helped =)
What is the answer to 8x-5 equals 23 plus 4x?
8x-5=23+4x 8x-5-4x=23+4x-4x 4x-5=23 4x-5+5=23+5 4x=28 4x/4=28/4 x=7
8x plus 23 plus 4x - 7x equals 68?
The answer is nine. Seriously. Here is my work if you don't believe me: 68=8x+23+4x-7x 68=8x-7x+23+4x 68=x+23+4x 68=x+4x+23 68=5x+23 68-23=5x 45=5x x=45/5 x=9
What is 8x - 1 -4x added to 23 x simplified?
15x -1 you first look for like terms and then combine them! (8x-4x+23x) = 15x then -1 = -1 giving you the answer!
-8x plus 4 equals -4x?
-8x + 4 = -4x; (-8+4)x = -4; x = 1.
What is the factor of 16xsquared-8x 1?
(4x - 1)(4x -1) or (4x - 1)2
How do you convert from 4x to 8x?
4x x 2 = 8x
How do you factor 4x squared minus 8x?
4X^2 - 8X factor out 4X 4X(X - 2)
What is the product of -4x and x plus 2?
ANSWER: -4X2 -8X-4x (x+2)= (-4x * x) + (-4x*2)= -4X2 -8X
16x2 plus 8x plus 1 equals 0?
16x2 + 8x + 1 = 0 : This factorises to (4x + 1)(4x + 1) = 0 When 4x + 1 = 0 then 4x = -1 : x = -1/4.
