3x - 12 = 10x - 15 - 6x -10

3x - 12 = 4x -25

3x + 13 = 4x

13 = 4x - 3x

13 = x

None?

Q: What is the mistake in this solving of an equation 3x minus 12 equals 10x minus 15 minus 6x minus 10 3x minus 12 equals 4x minus 25 3x plus 13 equals 4x 13 equals x?

y = -0.5x plus or minus any number

It is a quadratic equation with one unknown variable, x which has no real roots.

A quadratic equation, if there's an equals stil to come... Otherwise it's just an expression.

Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5

i think its 10

The idea is to find a number which, when square, equals the given number. For example, asking for the square root of 100 means solving the equation x2 = 100. The solution, in this case, is 10. (Minus 10 is also a solution, but the term "square root" refers to the positive solution in this case.)The idea is to find a number which, when square, equals the given number.
