What is the answer to 5x equals 2x plus 9?
5X = 2X + 9 subtract 2X from each side 5X - 2X = 2X - 2X + 9 3X = 9 divide each sides integer by 3 (3/3)X = 9/3 X = 3 ------------check in original equation 5(3) = 2(3) + 9 15 = 6 + 9 15 = 15 checks out
Is 2x-3 equals 15 an equation?
yes and the answr is x = 9
How do you solve 2x plus 3 equal 9 X equals?
The equation is 2(x) +3= 9. X would equal 3. The equation would now look like this, 2x3+3=9.
How do you solve this equation - 9 - 2x plus x equals - 13?
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
What is 3y-9 equals 2x in y intercept?
To put the equation 3y - 9 = 2x in y-intercept form (y = mx + b): 3y - 9 = 2x 3y = 2x + 9 (add 9 to both sides of the equation) y = 2/3 x + 3 (divide all terms by 3) The y-intercept is the b term in the equation, which in this example is 3.
What is 9 - (2x - 2) 9 - 3x?
It is a quadratic equation and its solutions are: x = -3/2 and x = 3
What is the answer to 5x equals 2x plus 9?
5X = 2X + 9 subtract 2X from each side 5X - 2X = 2X - 2X + 9 3X = 9 divide each sides integer by 3 (3/3)X = 9/3 X = 3 ------------check in original equation 5(3) = 2(3) + 9 15 = 6 + 9 15 = 15 checks out
5x equals 2x plus 27 x equals?
5x=2x+27 subtract 2x from both sides get get X on only 1 side of the equation. 5x-2x=2x-2x + 27 leaves you with 3x = 27 divide both sides by 3 3x/3 = 27/3 leaves you with x = 9 answer X=9
What is the answer to the equation 2x plus 3 equals 9 x equals?
21
Is 2x-3 equals 15 an equation?
yes and the answr is x = 9
How do you solve 2x plus 3 equal 9 X equals?
The equation is 2(x) +3= 9. X would equal 3. The equation would now look like this, 2x3+3=9.
How do you solve this equation - 9 - 2x plus x equals - 13?
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
How do you solve x plus 3 plus 2x equals x plus 9?
x + 3 + 2x = x + 9 x + 2x + 3 = x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 2x + 3 = 9 2x + 3 - 3 = 9 - 3 2x + 3 - 3 = 9 - 3 2x = 9 -3 2x = 6 2x/2 = 6/2 2x/2 = 6/2 x = 6/2 x = 3
What is 3y-9 equals 2x in y intercept?
To put the equation 3y - 9 = 2x in y-intercept form (y = mx + b): 3y - 9 = 2x 3y = 2x + 9 (add 9 to both sides of the equation) y = 2/3 x + 3 (divide all terms by 3) The y-intercept is the b term in the equation, which in this example is 3.
What is 2X 3 9 X?
2x 3 9 x ?
How do you solve 2x-6 equals 3x plus 3?
2x - 6 = 3x + 3: * Firstly, subtract 2x from both sides of the equation: -6 = x + 3 * swap the equation, so that "x" is on the left-hand side (to make things easier): x + 3 = -6 * subtract 3 from both sides of the equation, to give: x = -9
How would you solve the equation 4 over x-3 plus 3 over x equals -2x over x-3 giving step by step instructions?
If you mean: 4/x-3 + 3/x = -2x/x-3 Then multiply all terms by x-3: 4 + 3x-9/x = -2x Multiply all terms by x: 4x + 3x-9 = -2x2 Form a quadratic equation: 2x2+7x-9 = 0 Solve the equation by using the quadratic formula: Solutions: x = 1 or x = -4.5 Substitute these values into the original equation to ensure that the solutions are correct.
