If I understand the question correctly: 2x=39 then x=39/2 or x=19.5
2x+3=9 x
4x-39 = 2x+3, 4x-2x = 42 x=21
46
Instead of just giving you the answer, I will do steps. First: Let "x" be the number Therefore, 2x = 78. x = 78/2 x = 39 The number is 39
If I understand the question correctly: 2x=39 then x=39/2 or x=19.5
solv by cramr's rule [ 2x - 5y ] = 2 , [-4x + 10y ] = 1
x2 + 2x - 38 = 0 ∴ x2 + 2x + 1 = 39 ∴ (x + 1)2 = 39 ∴ x + 1 = ±√39 ∴ x = -1 ±√39
2x+3=9 x
This is 41x
Let the length of a leg be x. There are three sides: the base which is 11, and the legs, which are both x: 11 + x + x = 39 2x+11 = 39 2x = 39-11 2x = 28 x = 28/2 x = 14 The length of one leg is 14 units.
2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9
There can be no greatest common denominator. Suppose x is the greatest common denominator. That requires that 39 divides x, 26 divides x and x is the greatest such number. But 39 will divide 2x and 26 will divide 2x and 2x is greater than x. So x could not have been a GCD.
This is 41x
8x+39 = 2x-15 6x = -54 x = -9
2x + 6 + 9x = 39 11x + 6 = 39 11x = 39 - 6 11x = 33 x = 3
Your problem is 2x = 39. To figure out what x is, you first have to get rid of the 2 that is attached to the x. To get get rid of it, you have to do the opposite. In this case, that means you have to divide both sides by two. When I put parathesis around it, that means I'm dividing the whole thing by two. (2x = 39) / 2 = 19.5 So that means x=19.5
