When m = 3 the value of 3m is 3*3 = 9
3
2m = 3m = 3/2Therefore m = 1.5
3m^2 - 9m = 0 factor out 3m 3m(m - 3) = 0 m = 0 -------- or m = 3 --------
"3m" means "3 times m", so if m=9, then: 3m = 3 x 9 = 27.
To solve the equation 3m + 4 = 6m - 48, subtract 3m from both sides of the equation to get 4 = 3m - 48. Then, add 48 to both sides to get 52 = 3m. Finally, divide both sides by 3 to find the value of m, which is 17.
m = 7 3m-8=13 3m=21 m=21/3 m=7
3m+2=17 First, subtract 2 to get m on one side. 3m+2-2=17-2 3m=15 Divide by 3 to get m by itself. 3m/3=15/3 m=5 m equals 5.
-3m + 8 = 2 -3m = 2 - 8 -3m = -6 m = -6/-3 m = 2
81
9
If: 7+3m = -29 then the value of m is -12
They are equal. 1m = 100cm 3m = 300cm
