3x + 7 = 9x + 3
No solution one solution or infinite

One solution.  

Step-by-step explanation:

X=2/3 or x=2.6666

x=2/3

Step-by-step explanation:

3x + 7 = 9x + 3

Collect like terms (subtract 3x from both sides and subtract 3 f4=rom both sides)

The resulting equation will look like this:

 4=6x

=6x=4

Divide be 6 on both sides:

x=4/6

Simplify:

x=2/3 :-)

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
