Answer:

[tex]2\cdot h +(2.3\cdot k + 4)[/tex]

Step-by-step explanation:

This expression is solved algebraically:

1) [tex]2\cdot h -(-2.3\cdot k - 4)[/tex] Given

2) [tex]2\cdot h +(-1)\cdot [(-1)\cdot (2.3)\cdot k + (-1)\cdot (4)][/tex] [tex](-1)\cdot a = -a[/tex]

3) [tex]2\cdot h + [(-1)\cdot (-1)]\cdot (2.3\cdot k+4)[/tex] Distributive property.

4) [tex]2\cdot h +(2.3\cdot k + 4)[/tex] [tex](-a)\cdot (-b) = a\cdot b[/tex]/Modulative property/Result
