Answer:
[tex]u = 19[/tex]
Step-by-step explanation:
In order to solve for u, we must isolate the variable(u) with the constants(numbers). This means that the variable should be on one side, and the constant will be on the other which will allow us to get the numeric value for u.
Solving:
[tex]26~~~ = 2u~~ - ~~12 ~~(\text{add 12 to both sides to move it to the left side})\\\\(+12) ~~~~~~~~~~~ (+12)\\\\38 ~= ~2u ~~(\text{now divide both sides by 2 to get u and not 2u})\\- ~~~~~~-\\2 ~ ~~~~~~~2\\\\\boxed{u = 19}[/tex]
Therefore, the value of u is 19.
