it depends what you want to do with it...
if the number is x,
then it is
2x - 3=
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
The question contains an expression but not an equation. You cannot solve an expression.
This is an algebraic expression. It can be written as 3(2x + 4)
Twice the rational number 5/2 = 5From this, you need to subtract 4 3/5 to get 2/5.
It is: -3-(6) = -9
2x - 5 = 1Add 5 to each side:2x = 6Divide each side by 2:x = 3
2x - 6 = 3Add 6 to each side:2x = 9Divide each side by 2:x = 4.5
2 minus 5 is -3, sooo your answer should be negative 3 over 7.
Let the number be represented by ( x ). According to the problem, twice the number minus 3 equals 25, which can be written as the equation ( 2x - 3 = 25 ). Adding 3 to both sides gives ( 2x = 28 ), and dividing both sides by 2 results in ( x = 14 ). Therefore, the number is 14.
4x2 - 9 = (2x + 3)(2x - 3)
Write the statement as an algebraic equation. Then solve the equation.Twice a number: 2xThree times the number: 3xOne third the number: x/3In your question, you said: 2x - 3x = x/3 + 14Multiply each side by 3 ==> 6x - 9x = x + 42Combine the terms on the left side ==> -3x = x + 42Subtract 'x' from each side==> -4x = 42Divide each side by -4 ==> x = 42/(-4) = -21/2x = -10.5
The solution to 16 times 4 minus 8 times 3 times 0 is 64. The number name is sixty-four.
