Answer:

[tex]-0.75x-7-7.5x-5.4=-8.25x-12.4[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(-0.75x-7\right)-\left(7.5x+5.4\right)[/tex]

Remove parentheses:   (-a) = -a

[tex]=-0.75x-7-\left(7.5x+5.4\right)[/tex]

As we know that:  - (7.5x + 5.4) = -7.5 - 5.4

[tex]=-0.75x-7-7.5x-5.4[/tex]

Group like terms

[tex]=-0.75x-7.5x-7-5.4[/tex]

Add similar elements:  -0.75x - 7.5x = -8.25x

[tex]=-8.25x-7-5.4[/tex]

Subtract the numbers:  -7 - 5.4 = -12.4

[tex]=-8.25x-12.4[/tex]

Therefore, we conclude that:

[tex]-0.75x-7-7.5x-5.4=-8.25x-12.4[/tex]
