-(-2x-6y=-16)

2x+6y=16
4x-6y=-58

Y's cancel out, then add the rest

6x=-42

divide both sides by six

x=-7

plug x into any previous equation

2(-7)+6y=16

-14+6y=16

6y=30

y=5

Two classes have a total of 50 students. One of the classes has 6 more students than the other. How many students are in the lar

Ivahew [28]

Let's say 'x' to number of the students in the smaller class. Since the larger one is 6 more than the smaller one, its number would be 'x+6'. So their sum is equal to

$x+x+6=2x+6$ and we know total is 50 so:
$2x+6=50\\ 2x=50-6\\ 2x=44\\ x=\frac { 44 }{ 2 } \\ x=22$

x is 22 so the larger number 'x+6' is equal to : $x+6=22+6=28$
