Answers
let the no be x
x-2x/3= 20
3x-2x/3=20
x/3=20
x=60
.............................................................................................
STEP 1: Define x:
Let the number be x
.............................................................................................
STEP 2: Form the equation:
2/3 of x is 20 less than x
⇒ 2/3 x = x - 20
.............................................................................................
STEP 3: Solve x:
2/3 x = x - 20
Subtract 2/3 x from both sides:
0 = 1/3 x - 20
Add 20 to both sides:
1/3 x = 20
Multiply both sides by 3:
x = 60
