Answer:
-8x-9y
Explanation:
Hey There!
So basically this problem is asking you to simplify this expression using distributive property
The first step would be to distribute 7 into what is inside the parenthesis (2x and -3y)
2x*7=14x
-3y*7=-21y
so now we have 14x-21y + 4(3y-5x)
the next step would be to distribute 4 to what is inside the parenthesis (3y and -5x)
4*3y=12y
4*-5x=-20x
so now we have 12x-21y-20x+12y
the final step is to combine like terms
12x-20x=-8x
-21y+12y=-9y
so the simplified version of 7(2x - 3y) + 4(3y - 5x) is -8x-9y
