Question

twelve less than twice a number write the algebraic expression​

Answer 1

Answer:

2x-12 = 3- 3x

2x-12+12 = 3+12-3x

2x=15-3x

2x+3x = 15-3x+3x.

5x = 15.

5x/5 = 15/5.

x = 3.

Answer 2

Given,

Twelve less than twice a number.

To Find,

The algebraic expression for the given statement.

Assumption,

Let us assume, the number is x.

Solution,

We can simply solve the problem by moving with the words.

• Twice a number= 2x.
• Twelve less than twice the number= twelve is taken from it.
• meaning, 12 is subtracted from 2x= 2x-12.

Hence, the algebraic expression for the given statement is 2x-12.
