400/x-10x = 0
Multiply all terms by x: 400-10x2 = 0
Subtract 400 from both sides: -10x2 = -400
Divide both sides by -10: x2 = 40
Square root both sides to find the value of x:
Therefore: x = the square root of 40
Divide each side of the equation by 10 .
10x - 3 = 17 Add 3 to both sides: 10x = 20 Divide both sides by 10: x = 2
First, subtract 3x from each side of the equation. Then, divide each side of the equation by 7 .
-20=-4x-6x -20=-10x {collect like terms} x=2 {divide each side by -10}
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
well you divide by ten that's it the answer is 0.33333
Divide each side of the equation by 10 .
10x 2x divide 2x equals?
10x - 3 = 17 Add 3 to both sides: 10x = 20 Divide both sides by 10: x = 2
10x=x 9x=0 x=0
If: 10X = 2.7 then X = 2.7/10 => 0.27
-10x = -50 Divide both sides by -10 remembering that a minus divided by a minus the quotient then becomes positive: x = 5 So: -10*5 = -50
First, subtract 3x from each side of the equation. Then, divide each side of the equation by 7 .
11x = 10x-19 Subtact 10x fromboth sides:- x = -19
10x+7=(-3) 10x=(-10) x=(-1)ans
-20=-4x-6x -20=-10x {collect like terms} x=2 {divide each side by -10}
12x + 9 = 10x + 1 Subtract 10x from both sides: 2x + 9 = 1 Sutract 9 from both sides: 2x = - 8 Divide both sides by 2: x = -4
