Hey there!
To solve the equation 7+4u=70-3u,
the first thing you must do is to isolate the variable terms on one side of the equal sign. To do this, first subtract 7 from both sides and then add -3u to both sides:
7+4u=70-3u
-7 -7
4u=63-3u
+3u +3u
7u=63
Finally, to solve for the value of u, divide both sides by 7:
7u/7=63/7
u=9
Therefore, your final answer would be that u=9.
Hope this helps and have a marvelous day! :)
