2 (x - 5) = 3 (x + 2) so 2x - 10 = 3x + 6 so x = -16. Doesn't work.
Alternatively 2(5 - x) = 3 (x + 2) ie 10 - 2x = 3x + 6 ie 5x = 4 an d x = 0.8. Difference = 4.2, times 2 = 8.4 = 3 x 2.8.
The number is 0.8.

Three times the difference of a and m divided by twice their sum is equal to 6(a squared - m squared). 3(a - m)/2(a + m)
It is: 3x = 2x+8 and the value of x is 8
let the number be n. Then: 2n = 3n ⇒ 2n - 2n = 3n - 2n ⇒ 0 = n ie, the number is zero.
twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.
twice the difference of three times a number and eight
2x - 16 = 3x/18
A + 2a = 3a

2*(x + 21) = 3*abs(x - 5) => x = -5.4 or x = 57.
n + 2n = 3n
2x+x=3x
Three times the difference of a and m divided by twice their sum is equal to 6(a squared - m squared). 3(a - m)/2(a + m)
abs(2n - 7) = 3n/2 abs(2n - 7) may also be written as |2n - 7|
26 26 + 26 = 52 52 + 1 = 53
It is: 3x = 2x+8 and the value of x is 8
let the number be n. Then: 2n = 3n ⇒ 2n - 2n = 3n - 2n ⇒ 0 = n ie, the number is zero.
