The required two linear expressions are 4x+2x+9 and 6x+5+4

Linear expression

Given the expression 6x+9

We are to write two linear expressions that have similar expressions as this.

From the given expression,

  • 6x can be written as 2x + 4x

This shows that the expression can also be written as;

  • 6x + 9 = 4x+2x+9

  • Also we can write 9 as 5+4 to have ab equivalent expression 6x+5+4

The required two linear expressions are 4x+2x+9 and 6x+5+4

The two linear expressions that have a sum of 6x +9 are; 5x + 6 and x +3.

Linear expressions

The given expression; 6x +9 is already a linear expression.

However, we are required to write two linear expressions whose sum is 6x +9.

Hence, we can rewrite each term of the expression as a sum of two terms as follows;

  • 6x = 5x + x

  • 9 = 6+ 3

The required linear expressions are therefore; 5x + 6 and x +3.
