Question

7x - 3x = 24

Answer 1

7x - 3x = 24
The 7x and the 3x are both like terms, so they can be combined. 7 - 3 is 4, so the equation turns into
4x = 24
Now, you want to get the x alone, so you divide both sides by 4 because it is the opposite of multiplication. 24 divided by 4 is 6, so
x = 6

Answer 2

Answer:

x=3

Step-by-step explanation:

7x-3x=24

subtract 7 and 3 you'll get 4x=24

4x=24

divide each side by 4

x=3
