Answer:
x = 3
Step-by-step explanation:
x + 3 = 4x - 6
add 6 to both sides
x + 9 = 4x
subtract x from both sides
9 = 3x
divide 3 from both sides
x = 3
Let the number be x
(3/7) x = t
I can't think of anything useful to add to this. How about an example?
Let x = 49
(3/7) x = t
(3/7) * 49 = t seven will go into 49
3 * 49 = t
t = 147

Answer:
m=25w+80
Step-by-step explanation:
m=money
w=weeks
280-130=150
150/6=25 this is how much she earns per week
25*2=50 this is how much she earned in two weeks
130-50=80 this is how much she had before she worked
m=25w+80
plug in to check:
(25*2)+80=130
(25*8)+80=280
