10x + (8-x) = -19 10x + 8 = x - 19 10x = x - 27 9x = 27 x = 3
x/10x = 1/10 or 0.1
0
x2-10x = 0 x(x-10) = 0 x = 0 or x = 10
x2 + 9 = 10x x2 - 10x + 9 = 0. (x - 9)(x - 1) = 0. Therefore, x = 1 or 9.
-10x = x-33 -10x-x = -33 -11x = -33 x = 11
Depends on the value of x if x is 1 then 10x + 20 = 30 if x is 2 then 10x + 20 = 40 if x is 3 then 10x + 20 = 50 if x is 4 then 10x + 20 = 60 if x is 5 then 10x + 20 = 70 if x is 10 then 10x + 20 = 120 And so on
10x + (8-x) = -19 10x + 8 = x - 19 10x = x - 27 9x = 27 x = 3
x/10x = 1/10 or 0.1
0
10x=x 9x=0 x=0
Oh, what a happy little equation we have here! Let's bring some joy to this math problem. To find the value of x, we need to isolate it by moving the numbers around. Start by subtracting 1 from both sides, then divide by -10. And just like that, you've found the value of x - it's -8.
-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
( x^2 + 10x )^2 = ( x^2 + 10 x) ( x^2 + 10x ) = x^4 + 10x^3 + 10x^3 + 100x^2 = x^4 + 20x^3 + 100x^2 <----------------
-8 + 10x = 18 10x = 18+8 10x = 26 x = 26/10 x = 2.6
10x-1=35 is equal to 10x-1+1=35+1, or 10x=36 10x=36 is equal to 10x/10=36/10, or x=3.6
x2+10x-24 = (x-2)(x+12) when factored
