How do you solve 2x plus 2?
The solution to the equation 2x plus 2 is 2(x + 1).
Solution of equation 2x-5 equals 2-1?
2x -5 = 2-12x -5 +5= 2-1+52x = 62x/2 = 6/2x = 3
Is 2 a solution of the inequality 2x 5 9?
2 is a solution of the equation, but not if it's an inequality.
Identify the number of solutions to the quadratic equation 4x2 - 4x plus 1 equals 0?
4x2 - 4x + 1 = 0 => (2x - 1)(2x - 1) = 0 => (2x - 1)2 = 0 There is one solution: x = 1/2. It is a repeated root of the equation.
What is 2x-1 equals 1?
2x - 1 = 1 is a linear equation in one variable. If 2x - 1 = 1, then we can add 1 to each side of the equation and get 2x = 2, then divide both sides of the equation by 2, and we arrive at the answer, which is x = 1.
Which ordered pair is a solution to the equation y - 2x 6?
For example, if you have (0, 6) or (3, 1). Which of them is a solution to y - 2x = 6? Check (0, 6): y - 2x = 6, substitute 0 for x, and 6 for y into the equation 6 - 2(0) =? 6 6 - 0 =? 6 6 = 6 True, then (0, 6) is a solution. Check (3, 1): y - 2x = 6, substitute 3 for x, and 1 for y into the equation 1 - 2(3) =? 6 1 - 6 =? 6 -5 = 6 False, then (3, 1) is not a solution.
What is the solution to the equation 2x plus 4 equals 8?
2x + 4 = 8Subtract 4 from each side of the equation:2x = 4Divide each side by 2:x = 2
Solution of the equation 2x plus 3 equals 7?
2x + 3 = 72x = 4x = 2
Does x plus 2 equals 2x?
It does if x=2. That's the solution of your equation.
Is x equals 1 and y equals -4 a solution to the following equation y equals -2x?
No. -4 does not equal -2(1).
Is 0 -2 a solution of the equation 2x - 3y equals 6?
Yes.
Is -3 a solution of the equation 2x-5 equals 3x-2?
Yes
