Question

Which of these is a simplified form of the equation

7x + 4 = 5 + 4x?
a, 11x = 1
b, 3x = 9
c, 11x = 9
d, 3x = 1

Answer 1

Answer:

d

Step-by-step explanation:

We have to move all the x's on one side and all the numbers on the other side. To do that, we subtract 4x from both sides to get 3x+4=5.

Now, we have to subtract 4 from both sides to get 3x=1.
