It seems like there might be a typographical error in your equation "26x 74." If you meant to write an equation such as "26x = 74," you can solve for ( x ) by dividing both sides by 26. This gives ( x = \frac{74}{26} ), which simplifies to ( x = \frac{37}{13} ) or approximately ( 2.85 ). If you meant something else, please clarify!
To solve the equation (26x - 7x = 38), first combine like terms on the left side. This simplifies to (19x = 38). Next, divide both sides by 19 to isolate (x), giving (x = 2). Thus, the solution is (x = 2).
38 = 26x - 7x 38 = 19x (38/19) = x 2 = x
26x = 156 Divide both sides of the equation by 26 to find the value of x: x = 6
The answer to this equation would be 5. This is a math problem.

To solve the equation (-74x - 6 - 1 = 0), first combine the constants (-6) and (-1) to get (-74x - 7 = 0). Next, isolate (x) by adding (7) to both sides, resulting in (-74x = 7). Finally, divide both sides by (-74) to find (x = -\frac{7}{74}).
To find the points of intersection on the x-axis, set y equal to zero and solve for x. So, 8x^2 - 26x + 15 = 0. This is a quadratic equation that can be factored or solved using the quadratic formula. Once you find the values of x, those are the points of intersection on the x-axis.
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."
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.
you don't answer an equation, you solve an equation
26x-4 = 25 +4 +4 26x = 29 x= 29/26 or 1.115...
