P = 2(l+w)
substitute for P and l
12+8y = 2 (4x-2y+w)
distribute
12+8y = 8x -4y +2w
solve for w
subtract 8x from each side
12 +8y -8x = -4y+2w
add 4y to each side
12 +12 y -8x = 2w
divide by2
6 +6y-4x =w
the other side is 6+6y-4x

Answer: 30=2x+4 and there are 17 girls in the class.
Step-by-step explanation: if x+4=[total girls] and x=[total boys] and 30=[total kids], then x+4+x = 2x+4 = [total kids], since total kids id 30 then our equation is 30 = 2x + 4 and x= 13boys so 30-13= 17girls.
It's BASIC prealgebra so you should probably practice bit more with linear equations!
