If a positive integer, list the values of x which satisfy the equation 3x - 4 < 6 and x - 1 > 0
{1, 2, 3}
{2, 3}
{2, 3, 4}
{2, 3, 4, 5}
Forklaring
3x - 4 < 6 = 3x < 6 = 4
3x < 10
x < \(\frac{10}{3}\)
x < 3.33 and x - 1 = 0
n > 1 = 1< x; since x is an integer, and 1 < x3.33
x = {2, 3}
3x < 10
x < \(\frac{10}{3}\)
x < 3.33 and x - 1 = 0
n > 1 = 1< x; since x is an integer, and 1 < x3.33
x = {2, 3}
