What is the solution to the quadratic equation x2 plus 10x plus 25 equals 7?
Using the quadratic equation formula: x = -5-/+ the square root of 7
What is the solution of the equation x-12-25?
Without an equality sign the given expression can't be classed as an equation but it can be simplified to: x-37
3x plus 4y equals 90 4x-3y equals -5?
This is a simultaneous equation question. 4(3x+4y = 90) 3(4x-3y = -5) Multiply the top equation by 4 and the bottom equation by 3 then subtract the bottom equation from the top equation remembering that in maths a minus from a minus is equal to a plus. 12x+16y = 360 12x-9y = -15 And when subtracted: 0+25y = 375 Divide both sides of the equation by 25 to find the value of y: y = 15 Substitute 15 for y into the original equation to find the value of x: Solution: x = 10 and y = 15
What are all of the real or complex numbers that are solutions to the equation x2-25?
x2 - 25 = 0 is x2 = 25 thus x = 5 or x = -5, only 2 real solutions
What value of x satisfies the equation 2x plus 5 plus 3x equals 25?
2x + 5 + 3x = 25 5x + 5 = 25 Subtract 5 from both sides: 5x = 20 Divide both sides by 5: x = 4
Determine whether 25 is a solution of equation x-17 equals 11 is 25 a solution?
You can check an answer by substituting it into the equation. x - 17 = 11 25 - 17 = 11 8 = 11 Since this is not true, 25 is not the answer.

What is the solution of the equation x-8 equals 17?
x - 8 = 17x = 25 (add 8 to both sides)
What is the solution to the quadratic equation x2 plus 10x plus 25 equals 7?
Using the quadratic equation formula: x = -5-/+ the square root of 7
How many solutions ar there to equation 11x plus 25 equals 7x plus 15?
If: 11x+25 = 7x+15 then there is only one solution and it is x = -2.5
What is the value of k The equation x2-10x k0 has only one solution for x what is the value of k?
For the equation x2- 10x - k equals 0, you can solve this by knowing that if there is only one solution then the discriminant b2 - 4ac must be equal to 0. In this equation, a is 1, b is 10 and c is k This equation becomes 100 - 4k equals 0, and k is 25.
What is 5x plus 3 equal 28?
It is an equation of: 5x+3 = 28 and its solution is x = 5 5 times x plus 3 equals 28. Subtract 3 from both sides of the equation. 5 times x equals 25. Divide both sides of the equation by 5. x equals 5. (stop)
