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
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
n=3
8n = 160 n = 20
3 + 8n = -58n = -8n = -1
8n = 1 n = 1/8
8n + 11 = 41
8n = 72 n = 72 / 8 n = 9
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
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
n=3
3x - 5 = 48 So 3x = 53 and x = 53/3 = 17.66...
n=77
n = 1/2
x=4 or x=-4
