Question

3x-1=4 then 2x =

Answer 1

First solve for x in the first equation as in :

3x - 1 = 4

Bring the -1 to the other side as in adding 1 =
3x = 4 + 1
3x = 5
Divide by 3
x = 5/3

Then solve plug it into the next equation for x which is
2x = ?
2 (5/3) = ?
10/3

Answer 2

\[\sqrt{75} /2+ 3\sqrt{2}/4\]
