10x = 9x -25 10x -9x = -25 x = -25
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
3x2 - 10x - 8 = (3x + 2) (x - 4)
y - intercept = 10x - intercept = -10y- intercept: x = 0y = x + 10y = 0 + 10y = 10x - intercept: y = 0y = x + 100 = x + 10x + 10 = 0x = -10
x=5. 10x-4x (6x) +10-6x (=10) If 10 is 2x, x=5.
If: 10X = 2.7 then X = 2.7/10 => 0.27
11x = 10x-19 Subtact 10x fromboth sides:- x = -19
10x+7=(-3) 10x=(-10) x=(-1)ans
x=-8
You find x. Oh! There it is!! ^ See?
x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3
10x - 3 = 17 Add 3 to both sides: 10x = 20 Divide both sides by 10: x = 2
Rearrange: x2 - 10x + 25 = 0ie (x - 5)(x - 5) = 0x = 5Check: x2 = 25; 10x - 25 = 50 - 25 = 25. Job done
12x - 6 = 10x +2 12x - 10x = 2 + 6 2x = 8 x = 4
-10x = x-33 -10x-x = -33 -11x = -33 x = 11
8 = 10x/(10 + x) Multiply both sides by (10 + x) to give: 8*(10+x) = 10x Simplify: 80 + 8x = 10x Subtract 8x from both sides: 80 = 2x Divide both sides by 2: 40 = x
11x - 7 = 5 - xSubtract 'x' from each side:10x - 7 = 5Add 7 to each side:10x = 12Divide each side by 10 :x = 1.2
