I'll show work. X2-8x-4=0. X2-8x=4. X-8x=2. -7x=2. X=-(2/7).
7
If -8x+3=251, then 8x=-248. Therefore, x=-31.
2-8x=22 -8x=20 -x=2.5 x=-(2.5)
8x + 3 = 50 8x = 47x = 47/8x= 5 and 7/8ths
8 times 3 plus 32 equals 56. 8x + 32 = 56 8x + 32 - 32 = 56 - 32 8x = 24 8x / 8 = 24 / 8 x = 3
8x + 8=40 8x=40-8 8x=32 x=32/8 x=4
8x + 3 = 35 8x = 32 x = 4
8x + 32 = 0 8x = -32 (subtract 32 from both sides) x = -4 (divide both sides by 4)
no
2x2 = 8x x = 8x/2x x = 4 Check: 2(4)2 = 8(4) 2(16) = 32 32 = 32
No.
x² + 8x - 48 = (x + 12)(x - 4) x² + 8x + 48 = (4+(√32)i)(4-(√32)i)
No. That is because 2 - 8x is an algebraic expression, not an equation. And since it is not an equation, it does not have a solution.
no its not a solution
You add 8x to each side. This gives you 5 = 16. Since this has no solution, the original equation doesn't have any solution, either.
-6x-32 = 2x -6x-2x = 32 -8x = 32 x = -4
