8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4

subtracting gives 4x = -12 so x = -3

X=5/12

x = -8, y = 10

If the equasion is 12x+6-8x-4x-3+12 then the answer is 15.

8x+5=4x+17 4x=12 subtract 4x from right and 5 from left x=3 divide both sides by 4

8x + 15

8x + 9.16 = 4x + 16 8x - 4x = 16 - 9.16 4x = 6.84 x= 1.71

4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x

-8x + 4 = -4x; (-8+4)x = -4; x = 1.

8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3

8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.

no its not a solution

4x+8x+3 = 12x+3

8x-1 = -4x+23 8x+4x = 23+1 12x = 24 x = 2

16x2 + 8x + 1 = 0 : This factorises to (4x + 1)(4x + 1) = 0 When 4x + 1 = 0 then 4x = -1 : x = -1/4.

3x-3x+4x^2+8x=4x^2+8x

8x-2x+4x=10x

Only if 4 dollars plus 4 dollars equals 8 dollars.And if you had another 4x, you'd have a dozen-x.

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 =)

They don't. The line is parallel. ( 4x-8x=12 simplifies to y-2x+3, which has the same slope as y=2x+2)

If that's 8x - 4x = 12, it's an equation where x = 3

8x + 5z - 4x + 3z + 6 = 8x - 4x + 5z + 3z - 6 = 4x + 8z - 6

Add 1 to both sides. The answer is (4x + 1)(4x + 1) or (4x + 1)2
