Then you have N = 8
8n = 160 n = 20
3 + 8n = -58n = -8n = -1
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
n=3
n = 1/2
n=4. It's just like saying 8(4)= 32. I hope that helped
8n = 72 n = 72 / 8 n = 9
8n = 160 n = 20
3 + 8n = -58n = -8n = -1
8n = 1 n = 1/8
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
n=3
n = 1/2
8n + 3 = -29 8n = -32 n = -4
n=77
n = 1/2
n = (65 - 25)/8 ie 5
