Answer:
(a) 3m +4 = 6m
Explanation:
You want to know which of the equations is false when the value of the variable is 5.
3m +4 = 6m
3(5) +4 = 19 ≠ 6(5) . . . . . the given equation is false for m=5
-5(t -7) = 10
-5(5 -7) = -5(-2) = 10 . . . . true
17 = 4x -3
17 = 4(5) -3 = 20 -3 . . . . true
t +9 = 14
5 +9 = 14 . . . . true
