8 - 4 - 6 - 3 + 5 = 0
3+4m+5m=214m+5m=21-39m=18m=18/9m=2
4m+9+5m-12=42 9m=45 m=5
4m + 9 + 5m - 5 = 42 9m + 4 = 42 9m = 38 m = 38/9
M = 5 * * * * * 4m + m - 11 = 9 or 5m - 11 = 9 so that 5m = 20 and then m = 4, NOT 5.
simplified it equals, 9m+8
It is: 9m +8 -4m +7 -5m = 15
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
5m = 7 + 4msubtract 4m from both sides1m = 7m = 7=================================Oops. That first solution lost the '8' from the left side.An attempt to check the given equation with "m=7" fails.Try it like this:5m + 8 = 7 + 4mSubtract 4m from each side:m + 8 = 7Subtract 8 from each side:m = -1
4m + 9 + 5m - 12 = 42 Combining like terms to both sides:9m=42+12-9=>9m=45 divide both side by 9:m=5;
5m-13n-n+4m= (5+4)m+(-13-1)n= 9m-14n
you do some fun then do it
2n + 4m - 2n + m = 5m
