x2 = (26 + x)2
Taking square roots: x = +/-(26 + x)
Then x = 26 + x or x = -26 -x
The first gives a nonsense "equation" 0 = 26
but the second gives 2x = -26 or x = -13

Oh, dude, it's like super easy! So, if you have 86 plus x equals 112, you just subtract 86 from 112, and you get 26. So, the value of x is 26. Like, no big deal, right?
-8 + 10x = 18 10x = 18+8 10x = 26 x = 26/10 x = 2.6
If the equation is -4x + 2 = 26, then you can solve like so: -4x + 2 = 26 -4x = 26 - 2 = 24 4x = -24 x = -6 Check: -6 * -4 = 24, 24 + 2 = 26
