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
To solve the math problem 14 x 26, you multiply the number 14 by 26 as follows. First, multiply 14 by 6, the last number of 26. That gives you 84. Then multiply 14 by 2, which gives you 28. Since this answer goes in the tens column, rather than the units column, however, you need to add a zero, giving you 280. Then you add 84 and 280, which gives you 364, which is your answer.
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
