Answer:
Equation = 3x - 6 = 18
Solving of equation =
x = 8
Step-by-step explanation:
let the number be x
Now let us first set an equation
less than means - subtraction
3x - 6 = 18
Now let us solve the equation and find the value of x
3x - 6 = 18
Transpose
3x = 18 +6
3x = 24
x = 24 ÷ 3
x = 8
Equation = 3x - 6 = 18
Solving of equation =
x = 8
