-5(7m + 9) -7m
n=10/7. i did this one mentally. but are you sure its 8n minus negative 4n or is it 8n minus 4n? 8n- -4n does not equal 8n-4n 8n- -4n is the same as 8n+4n
It is: -3+8n-5 = 8n-8 when simplified
3 + 8n = -58n = -8n = -1

8n-5 = 3

7m
well, to figure that out, you need to have an equation with 8n in it. However, 8n is the same as 8xn
7m-5 = 9 7m = 9+5 7m = 14 m = 2
7m = 700cm, so 732cm is longer than 7m.
7m is.
