How do you solve 38 equals 26x - 7x?
38 = 26x - 7x 38 = 19x (38/19) = x 2 = x
26x equals 156 how much is x?
26x = 156 Divide both sides of the equation by 26 to find the value of x: x = 6
What is the solution of 20x 2-26x plus 8 0?
The answer to this equation would be 5. This is a math problem.
X2 plus 26x plus?
(x2 + 26x +) : syntax error.x2 + 26x
What number is needed to complete the square x2 plus 26x equals 0?
I'm hearing x2 + 26x + ? = 0 where you want to know what the ? would be for a perfect square binomial.I would be remiss if I did not mention that this is not the best method for solving this equation. First, the best method:x2 + 26x = 0First, just factor the x from the left side:x(x + 26) = 0Then x = 0 or -26. Problem solved, two answers.If you really want to complete the square, you can still solve it, but it takes a bit longer. Take half of the middle number (26) which is 13 and then square it. 132=169. That is your question mark. Don't forget to add it to the 0 to keep the equation balanced:x2 + 26x + 169 = 0 +169To finish solving:(x + 13)2 = 169x + 13 = +/-13x = -13-13 or x = 13-13x = -26 or x = 0. Same answer as above. A heckuvalot more complicated.* * * * *While all of the above is true, completing the squares is a very powerful way of solving general quadratic equations. It is implicitly the same as using the quadratic formula.The question can arise when you want to solve an equation such asx2 + 26x + 25 = 0The first step is to rewrite it asx2 + 26x = -25Now complete the square on the left, by adding 169 to both sides.x2 + 26x + 169 = -25 + 169 x2 + 26x + 169 = 144(x + 13)2 = 12Take square rootsx + 13 = ± 12so x = -13 ± 12so that x = -1 or x = 25The number 25 was chosen deliberately so that, after adding 169 there would be a perfect square. But the method works equally well otherwise.*****That is all true, but not the original equation and certainly not the most efficient way to solve it. I never claimed "completing the squares" was not "a very powerful way of solving general quadratic equations". I simply stated, "I would be remiss if I did not mention that this is not the best method for solving this equation."

What is a math equation that equals 23?
An equation is a statement, and is never 'equal to' a number.Here are a few equations that all have the solution [x = 23] :x + 3 = 26x - 7 = 165x + 7 = x + 99x2 - 26x + 69 = 0x (26 - x) = 69
Can you solve for a variable in an equation?
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
Do you answer an equation?
you don't answer an equation, you solve an equation

What is 26x - 4 equals 25?
26x-4 = 25 +4 +4 26x = 29 x= 29/26 or 1.115...
What are some ways to solve an equation?
solve it
What equation do you get when you solve 2x plus 3y 12 for y?
If you solve such an equation for "y", you get an equation in the slope-intercept form.
Can you solve the equation 3q 11 8q99?
It is not an equation if it does not have an equals sign. You could simplify it but not solve it.
