Answer 1

here is the answer mate...
2x+5x=200
by adding..
7x=200
by transposing..
we can get the value of x...
it's x=200/7

Answer 2

first point to note, this q is only 5 marks, not 50 
this is a type of cheating
never repeat it
second point, 2x+5x = 7x = 200
thus, x = 200/7 = 28.57 or 28.6



plz mark as brainliest
and give more points for qs in future
