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 an expression that can be simplified to -4n-1
n = -6
7 plus 7 divided by 7 plus 7 times 7 minus 7 is equal to 50.

A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9

98 + 7 = 105? ? ?
7 plus 7 divided by 7 plus 7 times 7 minus 7 is equal to 50.
It depends on the order of operations. 88, minus 22, plus 7, is 73. 88 minus (22 plus 7) is 88 minus 29, which is 59.
7 plus 7 divided by 7 plus 7 times 7 minus 7 is equal to 50.
Three plus three minus 7 is equal to -1
plus times plus = plus minus times plus = minus plus times minus = minus minus times minus = plus so when you subtract a number it is the same as adding its negative; for example 7 - 4 = 3 7 + (1)(-4) = 3
