It is an expression that can be simplified to -4n-1

8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4

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

3n - 9 + 4n = 8nCombine like terms:7n - 9 = 8nSubtract 7n from both sides:-9 = n

yes because the + and the - are two terms. hope this helps :3
