If you mean: 5x/7 -6 = x then x = -21
-19
It is 21/10 minus 1/10 = 20/10 or 2
minus 21 think of it as 12+9 which equals 21 then just whack a minus sign infront
-4 - 6 - (-10) = 0
6/7 minus 2/6 is 11/21
21
If: 24 = 6-x-3 Then: x = -21
21
If you subtract 15 from -6 you get -21. If you worked out the problem on paper, this is what it would look like. -6 - 15 = ? (change the minus to a plus, and change the sign of 15 from positive to negative) -6 + -15 = ? ( now you can add negative 6 plus negative 15 which equals negative 21) -6 + -15 = -21
4 x 6 - 3 = 21
6/7 - 2/3 = 18/21 - 14/21 = 4/21
6/7 - 2/3 = 18/21 - 14/21 = 4/21
3x-6 = 21 3x = 21+6 x = (21+6)/3 x = 9 You shouldn't ask us to solve your math homework.
