2*(x + 21) = 3*abs(x - 5) => x = -5.4 or x = 57.
abs(2n - 7) = 3n/2 abs(2n - 7) may also be written as |2n - 7|
26 26 + 26 = 52 52 + 1 = 53
Thrice A number divided by five is three
23
2
twice the difference of three times a number and eight
2x - 16 = 3x/18
A + 2a = 3a
18
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.
The square root of a number is the inverse of the square. For example, three squared equals nine, so the square root of nine is equal to three.
