Do you mean 3x = 45 then if so divided both sides by 3 to find the value of x which is 15
An equation to find the value of the variable 104, 137, 154 and x with a mean of 130 is: (104 + 137 + 154 + x)/4 = 130 395 + x = 130 * 4 x = 145.
5.
X is 6
It equals -36. To solve replace x with -6, because it is the value given in the problem and then just multiply. 6(-6)= -36.
To find the x or x's values
If you mean: x-8 = 3 then x = 11
If you mean: 6x = 25+x then x = 5
If you mean: x squared -14x +45 then when factored it is (x-9)(x-5)
If you mean: 5+2(x-1) = 12 then the value of x works out as 4.5
a/x = x/b Solve that proportion where x is the mean and a and b are the other 2 numbers. Your answer ends up being 3.6
Do you mean: 19.7-x = 7-2.2 then if so the value x works out as 14.9
If you mean: x squared -14x +45 then when factored it is (x-9)(x-5)
If you mean: x-3-4 = 0 then x = 7 I mean x + ln (x-3) - 4 =0
27 x x 8 Multiply 27 * 8 Multiply x * x 216 = x^2 Solve!
If you mean: 5+2(x-1) = 12 then the value of x works out as 4.5
If you mean: 14x = 129.5 then x = 129.5/14 = 9.25
