Answer:
[tex]7x - 8y + 18[/tex]
Step-by-step explanation:
To simplify the expression [tex]2(5x - 4y + 9) - 3x[/tex], we'll first distribute the 2 and simplify:
[tex]2(5x - 4y + 9) -3x[/tex]
[tex] 2 \cdot 5x - 2 \cdot 4y + 2 \cdot 9 - 3x [/tex]
So now our expression becomes:
[tex]10x - 8y + 18 - 3x[/tex]
Next, we'll combine like terms:
[tex]10x - 3x - 8y + 18[/tex]
[tex]= (10x - 3x) - 8y + 18[/tex]
[tex]= 7x - 8y + 18[/tex]
So, the simplified expression is:
[tex]7x - 8y + 18[/tex]
