Answer:
-5x + 14y
Step-by-step explanation:
[tex]\frac{2}{5} (10x-10y)-\frac{3}{4} (12x-24y)[/tex]
[tex]\frac{2}{5} (10x-10y)[/tex]
Multiply fractions: [tex]a*\frac{b}{c} =\frac{a*b}{c}[/tex]
[tex]=\frac{2(10x-10y)}{5}[/tex]
Factor 2 ( 10x - 10y)
[tex]=\frac{20(x-y)}{5}[/tex]
Divide the numbers: [tex]\frac{20}{5} =4[/tex]
= 4 ( x - y )
[tex]\frac{3}{4} (12x-24y)=9(x-2y)[/tex]
[tex]\frac{3}{4} (12x-24y)[/tex]
Multiply fractions: [tex]a*\frac{b}{c} =\frac{a*b}{c}[/tex]
[tex]=\frac{3(12x-24y)}{4}[/tex]
Factor 3 ( 12x - 24y )
3 ( 12x - 24 )
Factor 12x - 24y
[tex]=3*12(x-2y)[/tex]
Refine.
[tex]=36(x-2y)[/tex]
[tex]=\frac{36(x-2y)}{4}[/tex]
Divide the numbers: [tex]\frac{36}{4} =9[/tex]
[tex]=9(x-2y)[/tex]
[tex]=4x-4y-9(x-2y)[/tex]
Expand [tex]-9(x-2y)[/tex]
[tex]-9(x-2y)[/tex]
Apply the distributive law: [tex]a(b-c)=ab-ac[/tex]
[tex]a=-9, b= x, c= 2y[/tex]
= 9x - ( - 9 ) * 2y
= -9x + 9 * 2y
= 9x + 18y
Simplify 4x-4y-9x+18y
4x-4y-9x+18y
Group like terms.
=4x-9x-4y+18y
Add similar elements: 4x - 9x =-5x
Add similar elements: -4y +18y = 14y
= -5x +14y
