Other than a calculator:
The easiest way is to start by multiplying 26 by 10...you just add a 0 to 26 to get 260.
Then, since you want to multiply 26 by 14, but you've already multiplied 26 by 10, you need to now multiply 26 by 4 (fourteen minus ten is 4). Which is..104. Add this number to the number you got by multiplying 26 by 10, and you get a total of 364.
After doing this several times, you get the hang of it...I did that all in my head, for instance.

- 2x - 14 = 26 Switch all signs: 2x + 14 = - 26 Subtract 14 from both sides: 2x = -26 - 14 = - 40 Divide both sides by 2: x = - 40/2 = - 20
x+3=14 x+3-3 = 14-3 (subtract 3 from both sides to solve for x) x = 11
why will the equations x+14=37 and x-14=37 have different solutions for x
To solve for x means to find the value of an unknown number. For instance, in the equation x+14=23, the value of x is 9 because 9 is the number that needs to be added to 14 in order to reach the number 23.
X + 11 = 37. subtract 11 from both sides; X = 37 - 11 = 26.

Let the required number be x. According to question: When x is added to -26 we get 14. Therefore, x + (-26) = 14 x - 26 = 14 x = 14 + 26 = 40. So, 40 must be added to -26 to get 14.
x=28
-2x - 14 = 26 -2x = 26 + 14 x = -40/2 x = -20
x-2 = 14 x = 14+2 x = 16
364 is one answer 14 x 26 = 364 26 x 14 = 364 Half that also works ... 182/14 = 13 182/26 = 7
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
x=7
You don't solve this. It is an identity. 8X - 14 = 8X - 14 add 14 to each side 8X = 8X divide both sides integers by 8 X = X =============X can be any number you want.
364
how do you solve 14+x-11-x+x-3=1
One half X = 13 Double both sides: A whole X = 26 So, answer: X = 26
