Solving |7u+2|/4+u=u+2 and (2t+6)^1/2≥|t+1|-1

[math_student03]

hey guys, tried these problem for a bit but do not think I am on the right track, could someone help me get a lift off with these peoblems, thanks !

the first question:
Find all u satisfying the equation
u+2=|7u+2|/4+u

for this one i have tried to isolate u, then sub it into the quad formula.


And the second question is:
Find all t satisfying the inequality
(2t+6)^1/2 >(or equal to) |t+1| -1

and for this one i don't know where to begin =\

thank you !
