Correct
-7 (negative 7) transpose the 9x then transpose the 6. divide both sides by 3x and your answer will be -7 =]
X/7 = 6 multiply both sides by 7/1 (7/1)(X/7) = (6)(7/1) 7 cancels on left X = 42 ----------------check in original equation 42/7 = 6 6 = 6 ----------checks
the ANSWER is n = -7 how to get to it: step reasoning 6n=-42 given n=-7 divide both sides by 6
7a + 6 = -36 Subtract 6 from both sides: 7a = -42 Divide both sides by 7: a = -6 a = -6
Correct
The mean is 6.To get this answer you first add 5 and 7 which equals 12.Then you divide by how many numbers you added which is two.so you divide 12 by 2 which equals 6.
-7 (negative 7) transpose the 9x then transpose the 6. divide both sides by 3x and your answer will be -7 =]
Yes it can - divide BOTH numbers by 7 - and you get 6/14 which equals 3/7 !

6m = 42 Divide both sides by 6: m = 7
y/7 + 6 = 11 Subract 6 from bot sides: y/7 = 11 - 6 = 5 Multiply both sides by 7: y = 5*7 = 35
X/7 = 6 multiply both sides by 7/1 (7/1)(X/7) = (6)(7/1) 7 cancels on left X = 42 ----------------check in original equation 42/7 = 6 6 = 6 ----------checks

If -6d = 42 then 6d = -42. then divide by 6, d = -7
To solve 6x - 7 = 35, first you add 7: 6x - 7 + 7 = 35 + 7; i.e. 6x = 42. Then divide by 6: 6x/6 = 42/6, or x = 7.
